Re: Value of variable not appearing in the <xsl:other

Hi,

Another optimization to consider is to group using
group-adjacent="@class='analyze_visual'" returning a Boolean grouping key,
and groups that are nicely split.

Then part/@num should collapse into '{position()}' and things get simpler.
Also gracefully handles the case of multiple splits.

Cheers, Wendell
