These messages in log mean, that the SUBSCRIBE request didn't contain any known document types in Accept headers. There was a bug in PA module - it processed only the first Accept header, it was corrected on Friday, thus with actual CVS version it may work; but only in the case, that your client sends more Accept headers and one of them is known to PA module. If it will NOT work with actual version, please send me the message flow. thanks, Vaclav
