Attributes

abstract

Set to false (the default) when the element can appear in a document; true when this element can be replaced only with a member of its substitution group.

If block includes restriction, then the instance element’s type can’t be a restriction of the declared type. If block includes substitution, then the element can’t be substituted with a member of the substitution group.

final

Used to determine whether other elements can use this element as the head of their substitution group. If set to extension, then members of this element’s substitution group can’t have types that are extensions of this element’s type. If set to #all, then members of this element’s substitution group must have the same type as this element.

form

Takes the values qualified and unqualified. If qualified, the element must be used—with a prefix—in the schema’s target namespace. If unqualified, the element must be used without a namespace.
