[bdbxml] XQuery problem

Hi
I am trying to query across a container. Basically, the query is to have 3 
conditions. If ANY of these is TRUE, then return the result. 
************************************************************************
for $x in collection("bulk.dbxml")/gnv_enzyme_pathway/db_entry
let $m := $x/enzyme_id
let $s := $x/swissprot_reference_list/reference/@name
where some $r in $s
satisfies contains($r, "FABG1_BRANA")
return
<result>
<Enzyme_id id="{$m}"></Enzyme_id>
</result>
*************************************************

In this query, I need to add another condition, which will go like
.....
where some $r in $s satisfies contains($r, "FABG1_BRANA") OR if
$m="1.1.1.10<http://1.1.1.10>
"
return
.....

But, this is not working properly. Any ideas/suggestions how to add these 
conditions in xquery. 
I doubt if this question belongs to this mailing list; but, still if you 
have any idea abt it, please do let me know.

Regards
Manish
