I don't recall if I ever wrote it up, but part of my proposal for a @context
attribute was to have a context function, and it would take a parameter of
the number of levels upwards you wanted to go. context() would be 'the
current context', which would be the same as context(0), so to get the
"evaluation context of the parent bound node" you would do context(1).

This more general function would probably work in Leigh's example, and would
make his mark-up look like this:

  <repeat nodeset="a/b">
    <group ref="instance('other')/test[@name = current()/@name]">
      <group ref="context(1)">
        <output ref="."><label ref="@name"/></output>

The value of context(1) would be the next evaluation context up, which would
be the context for the first xf:group, which would be a/b[1], a/b[2], etc.
