[xmlsec] building without DTD validation support in libxml

Section 5.2.1 of the XPath spec has a NOTE that says "If a document does 
not have a DTD..."  So I don't think a DTD is required.

(This brings up my old issue, of course, since the second part of the 
note says that without a DTD no element will have a unique ID.  But how 
you're supposed to handle that when XPath also requires namespaces is, I 
guess, left as an exercise for the implementor.)
