I'd recommend trying to add the "filter" control mentioned here
http://simile.mit.edu/mail/ReadMsg?&msgId=23868
and then define a collection based on the default collection as follows
<div ex:role="collection" ex:baseCollectionID="default" id="filtered"
ex:expression="filter(value, .foo != '..')"></div>
And tie your map view to that new collection
<div ex:role="view" ex:collectionID="filtered" ... ></div>
