"A GetRecords request that omits all optional elements must produce a response containing only a summary of the result set. . . [should p]ass if all of the following conditions are true: (1) the response is schema valid; (2) the csw:SearchResults element is empty.]"

However, according to the spec, if there is no constraint specified, the "[d]efault action is to execute an unconstrained query." If this is the case, then shouldn't the test expect 12 results?



CSW GetCapabilities sections parameter

According to the OWS spec, "Server implementation of the Sections parameter is optional. When a server does not implement this Sections parameter, it shall ignore this parameter if present in a GetCapabilities operation request, and shall return the complete service metadata document."

Why do the CSW compliance tests check for the sections parameter?



CSW describerecord test

Assertion:      The response to a DescribeRecord request that contains an unknown TypeName element must not include any csw:SchemaComponent elements.


Is this correct? I would have thought a <csw:TypeName>csw:DummyRecord</csw:TypeName> would return an invalid parameter exception.
