> Key: XERCESJ-1285
> URL: https://issues.apache.org/jira/browse/XERCESJ-1285
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema Structures
> Affects Versions: 2.9.1
> Environment: WindowsXP, Java 1.5.0-b64
> Reporter: Martin Thomson
> Assignee: Sandy Gao
> Priority: Minor
> Attachments: test1.xsd

>
> If a base type includes an any declaration, within a sequence or choice that
> has non-unity cardinality, restrictions that specify more than one particle
> in place of the any declaration fail, even though their cardinality should be
> allowed as a sequence derivation based on NSRecurseCheckCardinality.
> This does not occur when the cardinality of the base sequence or choice is 1
> (i.e. minOccurs and maxOccurs both equal 1).
> Using Sandy's notation for single-element choices or sequences:
> base_c = (##any*|)*
> base_s = (##any*,)*
> Restrictions of these types that include multiple particles in place of the
> any fail.
> restriction_c = (X|Y)*
> restriction_s = (X,Y)*
> You can dupe Xerces into passing the restriction by adding two layers of
> extra groupings:
> restriction_c = (((X|Y|),)|)* -- passes
> restriction_s = (((X,Y,)|),)* -- passes
> But a simple grouping gets removed since it is a useless particle:
> restriction_c = ((X|Y|)|)* -- fails
> restriction_s = ((X,Y,),)* -- fails
> This probably has something to do with the way that Xerces removes redundant
> particles.
> Here's a schema that fails on all restrictions except the dupe ones (those
> with _p in the restriction type name). You can remove all instances of
> element Q to simplify the content -- it's there to show that this occurs only
> when part of the group is replaced. (My apologies for the size of this,
> there are a few cases to demonstrate).
> I get 18 total errors from this schema, but each restriction error results in
> two error messages from Xerces: rcase-Recurse.2 or rcase-RecurseLax.2 and
> derivation-ok-restriction.5.4.2.
