- Basic CQL2 (`http://www.opengis.net/spec/cql2/1.0/conf/basic-cql2`) defines the basic operations allowed in
the query language used for the `filter` parameter defined by Filter. This includes logical operators (`AND`, `OR`, `NOT`),
comparison operators (`=`, `<>`, `<`, `<=`, `>`, `>=`), and `IS NULL`. The comparison operators are allowed against string, numeric, boolean,

Filter class that binds Filter and Basic CQL2 to the Features resource (`/collections/{cid}/items`).
