Re: [xsl] Add id to next element

Thank you for the many suggestions!  I like the solution that process
<target> in a mode.  I will adapt it to the actual XML that I am
processing..

thatbs not the case then youbd have to do a little more work to only

But that would not be typical XSLT practice and would make it hard to find the
processing for <section>, which is obviously the primary component being
processed.
