I am looking for way to do somthing like:

if (lookup Ok) {
	var = value;
}

I am trying to generate alphabetical menu using xsltproc's possibilities.
Looking for XSLT2.0 documentation shown that its easy to do, but looks like
current libxml2 don't support 2.0 :-(

Look to http://www.FreeBSD.org/commercial/software.html for example.
There're two rules:

1. if vendor started with "letter" existing in the list, make this leter a
link to anchor "#LETTER_?"

2. if vendor supposed to output to Result Tree is a first vendor with a
"letter, add "<a name="LETTER_?">" before it. 

PS: Actually I am doing it as my first XSLT tutorial and looks like I found a
way how to do it, but I want to find most efficient way.
