[jira] Commented: (XALANJ-2411) XSLTC creates namespace nodes when it could re-use existing ones in scope.

Brian Minchau commented on XALANJ-2411:
---------------------------------------

In the testcase in the body of this issue I have these remarks:

Template 'makeElement1' makes sure that the default namespace is used 
rather than generating ns0 mapping to the same URI and using that.

Template 'makeElement2' also makes sure that ns0, ns1 ... sort of
prefix isn't generated, but also that the convenient prfx2 isn't used,
but rather that the default namespace is changed on this element.

Template 'makeElement3' makes sure that a new prefix is not generated,
and that the default namespace is changed. There is no possible re-use
of an existing prefix, so this differs from makeElement2.

> XSLTC creates extra namespace nodes, mapping ns0, ns1 ... to URIs when an existing namespace mapping is
> in scope and its prefix could be used (or the default namespace could be used).

> </xsl:template>
> 	
> </xsl:stylesheet>
> When run with any XML input, or this one, bug.xml:
> <?xml version="1.0" encoding="UTF-8"?><doc/>
> Using say the process command:
> java  org.apache.xalan.xslt.Process -XSLTC -IN bug.xml -XSL bug.xsl
> The output is this:
> <?xml version="1.0" encoding="UTF-8"?><out2 xmlns:prfx2="http://uri2" xmlns="http://uri1">
> <ns0:elemName1 xmlns:ns0="http://uri1"/>
> <ns1:elemName2 xmlns:ns1="http://uri2"/>
> <ns2:elemName3 xmlns:ns2="http://uri3"/>
> </out2>
> The output should be:
> <?xml version="1.0" encoding="UTF-8"?><out2 xmlns:prfx2="http://uri2" xmlns="http://uri1">
> <elemName1/>
> <elemName2 xmlns="http://uri2"/>
> <elemName3 xmlns="http://uri3"/>
> </out2>
