[Boost-users] namespace and directory name choice

hello,
technically, this is not a boost question.
I am writing a library to be used by third-party developers.
Internally, i use boost::mpl sequences.
Joaquin wrote mpl sequences cross-product metafunctions that i use,
i called them sequence2_cross_product and sequence3_cross_product
for the x-product of 2 and 3 sequences.

I put the metafunction in a separate header file. I don't intend to expose
it to my clients.

Is there an agreed convention/style as to where such a header file should lie?
My namespace hierarchy reflects my directory structure, so this is like asking
in which namespace should i put this metafunction.
I would have like to see such metafunctions already in boost::mpl.,
so should/can i highjack boost::mpl namespace in my header?
or put it at toplevel right below my namespace ?

rds,
