I think there is quite a misunderstanding...

I reformulate my thought: in the following example:


\testprefixattribute 3 = 4

\pdfprimitive\attribute 4=5

\pdfprimitive\testprefixattribute 3 = 4


to be compiled with luatex -ini:

we see that I enable the primitive attribute with no prefix, thus
\pdfprimitive\attribute works, until here all is ok. But I also enable
the primitive attribute with the prefix testprefix, so I expect the
same behaviour: \pdfprimitive\testprefixattribute should be working,
but it's not... So the question is: why? Is it normal that primitives
enabled with no prefix are considered by \pdfprimitive as primitives,
and not the ones enabled with no prefix? I tested also removing the
enabling of the attribute primitive with no prefix, it's the same, so
it does not come from enabling it twice, it comes from enabling it
with a prefix.

Thank you,
