Question... what effect (seemingly none) does the xmlns="" have?

I created this in error and sat staring at it.


Still can't get my head round it. Some sort of precedence?

No, xmlns="" is "special" in that it is the "undeclaration of the default namespace" directive.


It takes the default namespace *out* of the in-scope namespaces, rather than adding anything in.

In your case, it does nothing, because there was no default namespace to take away.

I hope this helps.
