Ok, so it should not be a primitive...

Hmmm now you say that it should be one... I don't really understand...

I know, but in TeXLive 2009, attribute does not exist for LaTeX (like
other luatex-specific promitives), so you cannot say
\pdfprimitive\attribute. What I wanted is to do the same with
luatexattribute, which is the only "primitive" (I still don't know if
it's one or not) available in TeXLive 2009 for LaTeX... It's not a
really big issue as it seems strangefor people to do such a thing as
\let\luatexattribute\hbox, but I report it in case it's a bug.

Thank you,
