XML Support in SQL Server 2005 has no dependency on http.sys
A recent blog post claimed that the native XML support in SQL Server 2005 has a dependency on http.sys and thus is only available on Win 2003 Server or Win XP/SP2.
This is incorrect. XML has no such dependency and should be available on all platforms where SQL Server 2005 is supported.
Only the HTTP/SOAP component has such a dependency.
