The best I can do is point to http://lists.w3.org/Archives/Public/www- tag/2002Dec/0119.html, which is the official XMLP WG response to the question of why SOAP 1.2 forbids DTD internal subsets. "Primarily, the reasons are (a) performance and (b) keep it simple. In the high performance regimes where some SOAP implementations will operate, the parsers will likely be tuned for SOAP message handling. Doing general entity substitution beyond that mandated by XML 1.0 (e.g. <) implies a degree of buffer management, often data copying, etc. which can be a noticeable burden when going for truly high performance. This performance effect has been reported by workgroup members who are building high performance SOAP implementations."
