time series representations in Mapserver

[Martin Tomko]

THis is quite like what I wanted to do with the SVG output.
But nobody gave me an answer whether it is possible to
a - get mapserver to include some attribute data in the SVG source 
(XML), let's say by specifying an attribute field in the dbf/database. 
This would result in a say a polygon with time stamps, or values, or so.
b - if there is a javascript way to access the svg source in the page 
and retrieve and change the value in the xml depending on another value 
of an attribute. This would enable to highlight a polygon with a 
specific value of an attribute. Dis anybody try something like that?
