Class IdAbuseChecker

java.lang.Object

com.sun.msv.reader.relax.core.checker.IdAbuseChecker

All Implemented Interfaces:

ExpressionVisitorVoid, RELAXExpressionVisitorVoid

public class IdAbuseChecker
extends java.lang.Object
implements RELAXExpressionVisitorVoid

makes sure that ID/IDREF are not abused. RELAX has the following constraint over the use of ID/IDREF.

First, ID and IDREF can be only used as attribute values. They cannot be used from type attribute of elementRules.

Second, if <tag> clause declares directly or indirectly (by referencing attPool) one of its attribute as ID/IDREF type, it must satisfies either (or both) of the following statement.

1. no other tag clause shares the same tag name.
2. no other attribute of non-ID/IDREF types shares the same attribute name.
