This is certainly not true with DB2.

I took a quick look at the documentation for SQL Server, Oracle, and 
Sybase. It does not appear that SQL Server or Oracle requires an XML 
Schema. I couldn't figure out whether Sybase requires one.

Note that Oracle is an odd bird here, as you can store XML either as a 
BLOB or using an object-relational mapping. The latter implies an XML 
Schema or DTD, but I don't know if it actually requires one.
