Extension for controlling output indenting

"John L. Clark" <[email protected]>
Newsgroups gmane.text.xml.xslt.extensions
Message-ID <20060228081232.GG10347@rejoice> 
The next thing in my queue for the Resources module has been
functionality allowing users to "turn off" indenting for particular
sections of the output tree.  For this, we've decided to go with an
attribute on the <xsl:output/> element called res:no-indent-elements.
I've come up with an initial specification.  This specification depends
on the existence of a generic "res:xml" output mode that allows for
extension.  I've written a brief spec that allows for this output mode,
as well.  The sources and HTML views for the first drafts of these
should be attached.

Take care,

    John L. Clark
