First, it seems to me that xmlSecAddChild() should call xmlSearchNsByHref() rather than xmlSearchNs() particularly for the case of Signature and its child elements. The logic of xmlSearchNs() seems to dislike searching against a namespace with a prefix attached when a prefix is not provided on the call. I'm reluctant to add that to a patch since it could have unknown impact.

Yes, this is a very good idea! I believe it would solve this problem
quite nicely though it might be a little slower :)


Second, the *easiest* patch for a namespace prefix is to create an xmlSecTmplSignatureCreateNs() function that has a prefix parameter and then have xmlSecTmplSignatureCreate() call that function with a NULL prefix value. Some don't like that style though. The only other alternative is to create a writable global string but that's a bit invasive too.
Sounds like xmlSearchNs() => xmlSearchNsByHref() change should do it
(assuming that user puts the namespace in the document by him/herself).
Though providing this helper function might be a good idea.

Lastly, a recent post mentioned you prefer patches based upon cvs. I can't find mention of cvs on your site.
