Entity resolution with catalogs and document()

[LEUZINGER Claude (DSIT-EX)]

the sun catalog  resolver (and URI resolver) works well with xalan-j 2.3. 
See ( http://wwws.sun.com/software/xml/developers/resolver/article/ ) 

But it does'nt work with this sample. ---pb with copy-of .. document( ..)
---
CRA_001.xml and CRA_002.xml DTD's are not resolved.


        <?xml version='1.0' encoding='UTF-8'?>
        <xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
        <xsl:template match = "/">
                <CRAset>
                <xsl:copy-of select = "document ('CRA_001.xml')"/>
                <xsl:copy-of select = "document ('CRA_002.xml')"/>
                </CRAset>
        </xsl:template>
        </xsl:stylesheet>

Is there some way to resolve this problem ?

Thanks.
