Low Description
A user using EC2MultiRegionSnitch, where the datacenter name has to match the AWS region names, will not be able to specify a keyspace's replica counts for those datacenters using CQL. AWS region names contain hyphens, which are not valid identifiers in CQL, and CQL keyspace/columnfamily properties must be identifiers or identifiers separated by colons.
Example:
CREATE KEYSPACE Foo
WITH strategy_class = 'NetworkTopologyStrategy'
AND strategy_options:"us-east"=1
AND strategy_options:"us-west"=1;
(see http://mail-archives.apache.org/mod_mbox/cassandra-user/201205.mbox/browser for context)
..will not currently work, with or without the double quotes.
CQL should either allow hyphens in COMPIDENT, or allow quoted parts of a COMPIDENT token.
