I had not time to read all sources but in valid.c is:

if ((elem->ns != NULL) && (elem->ns->prefix != NULL)) {

I thought that it pertinents to namespaces...

I used non-valid attribute value too, but it returns NULL too. For example
"newline" character(s) as a CR, LF or CRLF may be compensated by space.
Tabulators and other whitespace characters too.  Byt if I try set value to 
(for example): "a\nb\t\t\nc", it returns NULL too. This value is not valid.
