Michael Glavassevich resolved XERCESJ-1475.
-------------------------------------------
Resolution: Invalid
XML Schema processors operate over the XML Information Set [1] not the
serialized form of an XML document. There are no character references in the
Infoset. They will have been replaced by the XML parser with their character
code before an XML Schema processor ever sees them. The whiteSpace facet
defined in the XML Schema specification is applied to the Infoset value and so
what Xerces is doing is correct. Don't confuse this with the attribute value
normalization algorithm that is described in the XML 1.0/1.1 specs. That is an
entirely different process which occurs before the content of the document is
reported by the XML parser to the application or any other component (including
the schema validator) further down the pipeline.

> whitespace normalization for whitespace facet removes character references

> Key: XERCESJ-1475
> URL: https://issues.apache.org/jira/browse/XERCESJ-1475
> Project: Xerces2-J
> Issue Type: Bug
> Components: DOM (Level 3 Load & Save), JAXP (javax.xml.parsers), XML
> Schema 1.0 Datatypes, XML Schema 1.1 Datatypes
> Reporter: Martin Thomson
>
> Parsing an element that has a simple type with the whitespace facet set to
> collapse or replace results in character references being normalized.
> Character references must not be replaced or collapsed by whitespace
> normalization.
> For example, <x> a 
 b</x> should produce a value of " a \n b" in
> the PSVI. Instead, it produces "a b" if the whitespace facet is collapse
> (for example, when the type of <x> is xs:token). The character references
> are replaced prior to normalization and are not properly preserved.
> The description of the whitespace facet [1] does not make this immediately
> apparent, but it is relatively explicit in XML [2], though the text and
> example seem to be in conflict on the use of a character reference for the
> space character ( ).
