No, that's not part of the OWSContext schema. I participated in the OWS 
Context IE and don't remember the question of storing multiple zoom 
levels even being raised at all. Note that WMS doesn't support the 
concept of fixed zoom levels either, so before multiple zoom levels can 
be added to OWS Context some work will be required upstream in WMS.

If I remember correctly an extension mechanism was included in the 
schema that could possibly be used for that. I think Tom Kralidis would 
be the best one to answer on this. I CC'd him in case he is not on this
