You can't increment variables in XSLT like you do in procedural
languages like JavaScript. You usually don't need to do this.

For your specific problem, look up the generate-id() function:
 http://www.w3.org/TR/xslt#misc-func

If this doesn't quite fit (unlikely, but possible in some situations),
use a combination of hard-coded prefixes, generate-id(),
parameters passed through recursively processed templates and
perhaps position() and xsl:number
