How do I tell if a pageref is valid? In latex I could do something
like: \@ifundefined{r@label-\labelname} and I could tell if a label "labelname" was defined even if it was defined further on in the document (of course it would take a couple of passes to get it all right). How do I do the equivalent in texmacs? I need to generate conditional forward references - a reference to an additional block in a sequence, but only if the additional block is actually defined.
