what is the meaning of literals in step expressions?

I just realized that the existing grammar allows expressions such as "1/3",
"//book/2", and "/bib//46.5/editor". Do patterns such as these (with
literals in step expressions) have any valid semantic interpretation? What
should an XQuery implementation do on encountering such an expression?
Thanks,
Howard
