[Exist-open] &= and predicates

[<mi...@mc...>]

Hey all. I thought I'd mention this as its hard for me to say whether 
it's a bug
or not.

I have notice that when I string predicates together if I don't put the &=
expression the end then the search either times out or is insanely long 
(haven't
waited around to find out :)  )

In the following example $zone comes from (this example is fairly contrived as
the query is still a work in progress)

for $zone in currentDocument//zone
where $zone[.//* &= $OCCURENCE]
return(
count($zone//*[name(.) = "chercheur" or name(.)="date" or 
name(.)="notes"]                                                [. &= 
$OCCURENCE])
)

This works

count($zone//*[. &= $OCCURENCE][na0me(.) = "chercheur" or name(.)="date" or
name(.)="notes"])

This on the other hand would not.


I haven't had a chance to test this on a smaller example, but, I thought I'd
bring it to your attention.

Thanks for all the hard work,
Mike
