[oXygen-user] rewrite statements in catalog

[Radu Coravu]

Dear José,

We understand your use-case and indeed the Author page could be improved 
to try and resolve the unparsed entity SYSTEM through the URI resolver 
and use the result to display the image.
On the other hand, I do not think this is consistent with the output of 
an XSLT transformation.
 From what we tested, both the Saxon 6 and Saxon 9 XSLT transformers do 
not try to go through catalog when solving the unparsed entity using the 
"unparsed-entity-uri" method.
Here are some small samples:

catalog.xml:
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
    <!-- This is a sample -->
    <uri name="http://www.oxygenxml.com/lake.jpeg" uri="../lake.jpeg"/>
</catalog>

test.xml:
<!DOCTYPE root[
<!ENTITY ENT SYSTEM "http://www.oxygenxml.com/lake.jpeg" NDATA JPEG>
]>
<root ref="ENT"></root>

test.xsl:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0">
    <xsl:template match="//root">
        <xsl:value-of select="unparsed-entity-uri(@ref)"/>
    </xsl:template>
</xsl:stylesheet>

 From what I understand from the specifications the unparsed entities 
are not solved through catalog.
See: http://www.w3.org/TR/xslt#unparsed-entities
Do you plan to perform additional processing of the XML file before 
transforming?

Regards,
Radu
