[xsl] Doctype and namespaces in source/generated files

[Mayo <mayo@xxxxxxx>]

Hello,

I'm trying to process and output xhtml documents, but I'm having some  
problems with namespaces. Each source document has extra namespace(s)  
(other than the xhtml one) for custom tags (the ones that the xslt  
stylesheet will be processing).

The xslt I'm using matches elements in undefined namespaces, and copies  
those into the output, and processes the elements in my custom  
namespaces. (In other words I want to copy everything other than my  
custom namespaces, and process what's not copied)

the match rule i'm using is:
<xsl:template match="*[not(namespace-uri())]">
than I simply xsl:copy, and apply templates. This prevents me to  
specify DOCTYPE or namespaces for xhtml in the source documents, as as  
soon as I specify them (in the source documents) the match rule will  
stop working, and strips all my xhtml out.

My quesiton is, is there a better way to do this, or is there any easy  
way that I can manipulate what namespaces/doctypes the output files  
will have? (I want to strip out my custom namespaces, preserve any  
other ones, add the xhtml one, as well as add a doctype to the  
generated document).

Ideally, I would like to specify doctype and all the proper namespaces  
in the source files.

I've been looking over the "XHTML to XHTML transform"  
(http://www.biglist.com/lists/xsl-list/archives/200404/ 
threads.html#00067) thread from few months ago, but I can't seem to  
figure out how the input/output namespaces (and doctype) were handled  
there.

thanks,
