Nesting predicates and context node

Hello everyone,

how do I use nested predicates and refer from the inner predicate to the
current node of the outer predicate?

For example:
    //product[count(preceding-sibling::product[@id= ? ]) < 3]

The question mark stands for an expression that selects the @id of the
outer context node. The 3 at the end is a variable that gets set from an
application actually. This expression would be used to set the value of
an xsl:variable. I need to to know if it is possible to refer to the
current node of the outer predicate or if I can achieve a solution wth a
completely different approach.

Thanks for any help. Martin.
