Re: [xsl] Passing parameters to an indirectly called template after matching.

[Kannan <riderchap@xxxxxxxxx>]

Thank you Michael and Abel.  I got it working with 2.0. I think I will
start using XSLT 2.0.

The infinite loop solved when I gave a default value for the
parameter, very novice to XSLT to know why, but its working now.
