These are just auxiliary sets of parameter entity definitions, not
substantive tagsets in their own right, hence you won't find the sort of
definition I suspect you have in mind. Use of one or the other of them
doesn't give you access to any elements or attributes other than those
defined elsewhere: it merely allows you to draw on more than one base
tagset, while specifying how and where ingedients from those bases can be
mingled in your documents.
So they offer two different ways of handling situations in which you need to
incorporate elements and attributes from more than one base tagset into your
DTD (and if you don't need to do that because an existing base meets all
your needs, you can forget about them). Their use is explained in P4 3.2.2
and 3.4 , as is the distinction between them.
If you use the mixed base plus the base sets of your choice, you can use
chunk and inter-level elements from any of your chosen base sets in any div
in any part of your text. This may well be more permissive than you need or
want. Using the general base allows you to have a number of sections within
a text, each of which draws on one (only) of your chosen multiple component
bases for its repertoire of permitted elements. This gives you more control
over what appears where.
But P5 promises more flexible and less confusing ways of dealing with such
