New Revision: 390
Modified:
trunk/protocol/tapir.xsd
Log:
Changed filter capabilities so that implementations either accept all filter functionality or none:
* Renamed element /response/capabilities/operators to "filter" and included an optional subelement called "encoding".
* Renamed "boolean" to "booleanOperators", and made all logical and comparative operators mandatory.
Now parsers can always rely on the existence of a <filter> element in the capabilities response and then pass it to a specific handler (such handler can just detect if there's an element "encoding" or not, which means "I understand the basic filtering mechanism" or "I don't know how to parse any filters").
