Using context() within calculate or relevant binding

Is there a reason why you cannot use the context() function within a bind statement? I have a need to create a calculation that depends on statements like this where I have to switch context:

// example for illustration purpose calculate="Parent/GrandParent[@Gender <> context()/@Gender]/@Age"

I've attached a simple testcase. If it is not possible, what is commonplace for calculations or relevancy checks that involve looking at values inside another portion of the xml hierarchy using a piece of information of the current hierarchy to form your selection.

Jeremy,

You may be hitting this bug:

http://forge.ow2.org/tracker/index.php?func=detail&aid=315688&group_id=168&atid=350207

You could write something like:

calculate="for $context in . return Parent/GrandParent[@Gender <>
$context/@Gender]/@Age"
