Re: [xsl] Seeking a smarter tokenize for augmented text

Hi Trevor,

If the markup in the lines doesn't stretch across line breaks, you can 
insert empty elements for each line break using xsl:analyze-string in a 
first pass.

In the second pass, you then group the nodes below textlines, starting 
or ending with such an empty linebreak element that you introduced in 
the first pass.
