[XERCESC-2193] Validation error for prefix declaration on element whose value uses a prefix

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 3.2.2
• Component/s: Validating Parser (XML Schema)
• Environment: Linux

Description

Xerces schema validation reports the prefix is undefined when QName content of an element is using a prefix defined on the element (works fine with Xerces-J, etc).  

<link:usedOn xmlns:this="http://example.com/this">this:someArc</link:usedOn>

validation message: undefined prefix in QName value 'this:someArc' 

Is there a parameter, usage pattern, or code patch which will make this validate cleanly?  (isPrefixUnknown seems to look in element stack instead of looking first at current element?)
