RE: [xsl] Changing row colors using variables

[Steve Kuntz <SKuntz at CooperVision dot com>]

I know that I can't assign a variable like that...and the logic for the
colors is more complex than every other row. My table will be sorted based
on a certain attribute, and I want all like attributes colored the same.
Sounds like maybe there is no way to do this.
