Element and Attribute Namespaces
Global element and attribute declarations belong to this schema's target namespace.
By default, local element declarations belong to this schema's target namespace.
By default, local attribute declarations have no namespace.

This type represents the Field type as described in the
documentation, i.e. that a field has: (i) a set of Samples, and (ii) an set of rules
to reconstruct the continuity of the field in the spatial domain (a spatial
interpolation function, or different functions)

This type will most likely contains a TIN for which there
are no rules to automatically construct it. For instance it was created
manually by a user. The gml:CompositeSurface and the Points are stored
separately because it becomes extremely complex to extend the types
needed (gml:Polygon doesn't use gml:Point, but gml:pos... so where does
one start creating new type? For the whole hierarchy?)

The minimum and maximum occurrence of elements and attributes are provided in square brackets, e.g. [0..1].
Model group information are shown in gray, e.g. Start Choice ... End Choice.
For type derivations, the elements and attributes that have been added to or changed from the base type's content are shown in bold .
If an element/attribute has a fixed value, the fixed value is shown in green, e.g. country="Australia".
Otherwise, the type of the element/attribute is displayed.
If the element/attribute's type is in the schema, a link is provided to it.
For local simple type definitions, the constraints are displayed in angle brackets, e.g. <<pattern = [1-9][0-9]{3}>>.
If a local element/attribute has documentation, it will be displayed in a window that pops up when the question mark inside the attribute or next to the element is clicked, e.g. <postcode>.

Abstract
(Applies to complex type definitions and element declarations). An abstract element or complex type cannot used to validate an element instance. If there is a reference to an abstract element, only element declarations that can substitute the abstract element can be used to validate the instance. For references to abstract type definitions, only derived types can be used.
All Model Group
Child elements can be provided in any order in instances. See: http://www.w3.org/TR/xmlschema-1/#element-all .
Choice Model Group
Only one from the list of child elements and model groups can be provided in instances. See: http://www.w3.org/TR/xmlschema-1/#element-choice .
Collapse Whitespace Policy
Replace tab, line feed, and carriage return characters with space character (Unicode character 32). Then, collapse contiguous sequences of space characters into single space character, and remove leading and trailing space characters.
Disallowed Substitutions
(Applies to element declarations). If substitution is specified, then substitution group members cannot be used in place of the given element declaration to validate element instances. If derivation methods , e.g. extension, restriction, are specified, then the given element declaration will not validate element instances that have types derived from the element declaration's type using the specified derivation methods. Normally, element instances can override their declaration's type by specifying an xsi:type attribute.
Key Constraint
Like Uniqueness Constraint , but additionally requires that the specified value(s) must be provided. See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions .
Key Reference Constraint
Ensures that the specified value(s) must match value(s) from a Key Constraint or Uniqueness Constraint . See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions .
Model Group
Groups together element content, specifying the order in which the element content can occur and the number of times the group of element content may be repeated. See: http://www.w3.org/TR/xmlschema-1/#Model_Groups .
Nillable
(Applies to element declarations). If an element declaration is nillable, instances can use the xsi:nil attribute. The xsi:nil attribute is the boolean attribute, nil , from the http://www.w3.org/2001/XMLSchema-instance namespace. If an element instance has an xsi:nil attribute set to true, it can be left empty, even though its element declaration may have required content.
Notation
A notation is used to identify the format of a piece of data. Values of elements and attributes that are of type, NOTATION, must come from the names of declared notations. See: http://www.w3.org/TR/xmlschema-1/#cNotation_Declarations .
Preserve Whitespace Policy
Preserve whitespaces exactly as they appear in instances.
Prohibited Derivations
(Applies to type definitions). Derivation methods that cannot be used to create sub-types from a given type definition.
Prohibited Substitutions
(Applies to complex type definitions). Prevents sub-types that have been derived using the specified derivation methods from validating element instances in place of the given type definition.
Replace Whitespace Policy
Replace tab, line feed, and carriage return characters with space character (Unicode character 32).
Sequence Model Group
Child elements and model groups must be provided in the specified order in instances. See: http://www.w3.org/TR/xmlschema-1/#element-sequence .
Substitution Group
Elements that are members of a substitution group can be used wherever the head element of the substitution group is referenced.
Substitution Group Exclusions
(Applies to element declarations). Prohibits element declarations from nominating themselves as being able to substitute a given element declaration, if they have types that are derived from the original element's type using the specified derivation methods.
Target Namespace
The target namespace identifies the namespace that components in this schema belongs to. If no target namespace is provided, then the schema components do not belong to any namespace.
Uniqueness Constraint
Ensures uniqueness of an element/attribute value, or a combination of values, within a specified scope. See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions .
