/**
* Decorator for PropFindRequestFieldParser's.
*
* Calls getRequestedFields on the wrapped object. If no fields were requested
* this class adds the default ones expected
* by windows clients. This is because windows clients generally do not
* specify a PROPFIND body and expect the server to return these fields.
*
* Note that failing to return exactly the fields expected in the exact order
* can break webdav on windows.
