If Processing Instructions can appear anywhere withing an XML document, then there is no reason why XP needs to keep that restriction. As far as DTDs go, I personally feel their use should be deprecated in favor of schemas. While I understand this may not be possible at this time, I do not feel we need to neuter the spec in order to support DTDs. If you need to send an XML message that has a DTD, then either encode it or refer to it by reference. David Cleary Progress Software
