disallowedSubstitutions Property
Returns an enumerated value from the SCHEMADERIVATIONMETHOD declarations. The possible values are SCHEMADERIVATIONMETHOD_SUBSTITUTION, SCHEMADERIVATIONMETHOD_EXTENSION, and SCHEMADERIVATIONMETHOD_RESTRICTION. The returned valued specifies whether an element declaration that appears in a content model will be prevented from additionally validating elements.
Validation might be prevented for one or both of the following two reasons.
- The additional element contains an
xsi:typeattribute that identifies an extension or restriction for the type of the declared element. - The element is in the disallowed substitution group. This group has had a substitution performed against it using the element that has a declaration with the
disallowedSubstitutionattribute.
