<xsl:variable name="some_var" select="'some value'"/>

The value of the select attribute may be an XPath expression, number or
literal string.  If you omit the select attribute:

<xsl:variable name="some_var">some value</xsl:variable>

then the contents of the xsl:variable element provide the value.  This is
invariably a string (or a result tree fragment, which in practice is the
same thing).

And the FAQ, among other places:

Ah, now we're getting somewhere.  You can't do a counter in the procedural
sense, because XSLT variables can't be updated with new values once bound.
You can, however, implement a loop (as one example requiring a counter)
using recursive techniques: http://www.dpawson.co.uk/xsl/sect2/N5019.html

I'm not the first to say this, but you can't just invent syntax for a
language and expect it to work.  I recommend perusing the above-mentioned
FAQ or finding a good tutorial book for learning XSLT.
