Section 4.6.9 'Query Object'. Clarify what Query.getLanguage() returns if the
query was created using JQOM. Query.getStatement() will return a string
representation in JCR-SQL2. Should getLanguage() return JCR-SQL2 or JCR-JQOM?
I think it should return JCR-SQL2 because that's what getStatement() will
return. If we specified it that way then the constant Query.JCR-JQOM is probably
useless and can be removed.
