[xml] string interning in recent libxml2 releases?

[Chris Ryland <cpr emsoftware com>]

Daniel--

I can't find anything in the most recent tree API docs about it (quick 
scan--perhaps I missed, but I don't know what search terms to use), but 
I thought I saw somewhere that late releases have some kind of string 
interning for element/attribute names. Is that true, and, if so, can 
one share the interning so we can compare string pointers instead of 
comparing strings, when walking the doc tree?

Any hope? ;-)

Thanks & cheers!
