In the Catalog Service v2.0.2 the geooperation names were corrected. This is the new syntax rule:
geoop name ::=
EQUALS | DISJOINT | INTERSECTS | TOUCHES | CROSSES
Nowadays the CQL tokens are:
EQUAL, DISJOINT, INTERSECT, TOUCH, CROSS, WITHIN,CONTAINS, OVERLAP RELATE
So the parser should be update with the following
EQUALS, INTERSECTS, TOUCHES, CROSSES, OVERLAPS
It is ok in ECQL.
