No, as the context is a single <Product> node...

Doing what you are after is simple is XSLT 2.0, you could just use
select="1 to $quantity".

In 1.0 it's a lot harder, you will need to write a recursive named
template that calls itself decrementing the count with each call, or
use the Piez 'hack' of select="$someElementList[position() &lt;= 5]"

As you haven't said if you can use 2.0 or not, I won't expand on the
1.0 solutions until then :)
