Re: [xsl] Displaying column headers only if variable changes

["Dennis Daniels" <ddaniels at magic dot fr>]

Hello Brian
You're building UML diagrams, yeh? My I ask with what tool? What format is
your diagram coordinate data being saved in? SVG? PGML? custom xml? I ask
because I'm currently working on an xslt for pgml to svg (btw if anyone else
has done similar I'd love to hear from you!) for www.argouml.org
thanks
Dennis

As you see in the code, right now I'm printing what lastDiagramType is
changed to, for debug purposes, and it never changes. It stays "LAST" as I
default set it, but it is hitting that code.
