Comments and questions concerning draft 0.98, directory layout

[K. Berry]

    i think its sort of up to the author to lay claim to a new format or
    not. texinfo clearly does. maybe Taupin does, maybe he doesnt. can
    you somehow express that argument in the TDS docs? 

Well, I added a parenthetical:

Although some formats (e.g., Texinfo, Eplain) can also
be used as macro packages, the \abbr{TDS} nevertheless stores them as
formats (at the option of the format author).

If someone thinks more is needed, speak up (with specifics :-).
