How to filter children by processing in XSL:

It's not as clean as we would like as things stand. The following
(untested) is messy but should work with XSLJ:

<define-script>
var thresholdDate="1/1/94";
function myFilterPred(node) {
return dateGreater(node.entrydate,thresholdDate);
};
function dateGreate(d1,d2) {
. . .
}
</define-script>

<rule>
. . . some pattern . . .
<eval>if (myFilterPred(this)) {
return withMode(OK,processNodeList(this));
}
else {
return <empty/>;
};
</eval>
</rule>

<rule mode='OK'
. . . same pattern . . .
... action to format the nodes which are passed by the filter ...
