Depending on what you want to do with the number, you may be able to use 
the <xsl:number/> instruction.  This puts the number directly into the 
result tree, so it can't (for instance) be used in a select expression, but 
if you're just trying to number the items, it may help.

[There's been a discussion over in XML-L on the benefits and drawbacks of 
<xsl:number/> if anyone's interested.]
