No, you don't need it (Side effect free languages are provavbly as
expressive as procedural languages).

No you need to generate a number based on some property of the
input. You just need to specify what that function is.

If you said what the function is then someone could probably suggest
an XPath expression (probably in conjunction with xsl:number)
that would work.

If you did use an extension function to get the side effect of counting
or used saxon:assign then note that you would have no assurance that
you got the value that you want. templates may be evaluated in any
order, or in parallel. There is no assurance that the system builds the
tree in the same order that it is output.
