[odb-users] ODB Named pragmas

Hi all,

I am checking the ODB Manual and I saw in 14 ODB Pragma Language Chapter 
that is possible to make use of #include directive to include the file 
with the odb pragma. But, I wondered if it is possible to do the other 
way round, to avoid putting odb things in the source header file. Let's 
take the example shown in the manual:

    // person.hxx
    class person
    #ifdef ODB_COMPILER
    # include "person-pragmas.hxx"

And I would like to have:

    // person.hxx
    class person

    // person-pragmas.hxx

    #include "person.hxx"

    #pragma db object(person)
    #pragma db member(person::id_) id

I must admit that I did not tried yet, I just wanted to confirm with you 
if it is possible and If it would have any side-effect before going into 
this approach.

Thanks in advance,
