It works (interestingly, as I found answers all over the web
specifically stating that this could not be done, e.g. that an XSLT
variable is actually a constant which's value cannot be changed once
defined), but I needed to insert a space between "$pos" and "-1" as
otherwise the variable name would be interpreted as "pos-1", which is
not defined.

Thanks!
