feature request; id idref pairs

Some time back it was noted that it might be
useful to be able to obtain the node which refers
to a particular id value.

This would be the reverse of id().
Returns a node list.

Use case.

In plain text or braille versions of a flowchart,
the required notation is

box-number (origin-of-link): box-content -> (target-of-link)

or for decisions

box-number (origin-of-link): box-content. Yes  -> (target-of-link). No ->
(target-of-link).


I can find the target-of-link using id(@link)/@id

Today I can't find the nodelist which calls any particular box.


Could this be considered for a future version of XSLT.
(meanwhile maybe as an extension function Michael, James?)
