it turns out that there is no simple way of having the datatype of a constant geometry available in the query builder, thus it is not easy for geof:getSRID to determine the correct datatype and return the appropriate URI for the CRS, when that has SRID 4326. Therefore, we choose to always return CRS84, even for strdf:WKT arguments. Notice, that when geof:getSRID is called evaluated in Java, we have such information available and we can return the correct result. However, we chose in changeset 1420:37792dd7041b to always push the evaluation of all spatial functions in the database. The respective tests have been updated as well.
