I'm reasonable (or at least usually ;-)) more than enything else, I'm
a pragmatist.

Perhaps. I like "an atomic unit of information" as a definition, from
which your list can be derived.

Note this. I am lax in terminology, but this is an important concept.

Ahhh....

This goes back to early last year... but the above are *indicative*
anyway. Please take my paper with a pound of salt as it contains many
terminological inexactitudes (lies??? ;-))

Abstract. Not hard.

Yup. Sadly, people often look at the words as a way to understand the
concepts, and words are such personal things....

Perhaps. I put it as a string rather than an enum simply to allow the
easy stuff to be done *now* an the hard stuff later.

Ma ne. Sono language no parameta ha hotondo Unicode no tame...

This is *OK*, but it doesn't handle thinks like litigatures very
well.

Zen. It's Zen...
