This is an absurd claim, and I assume it should be taken as
Religious Rhetorick, but if there is really a misunderstanding,
it's worth clearing up.

Calling a piece of software that processes data an application does not
in any way imply that software and data are inseperable.  It is merely
a difference in terminology.  Author/Editor is an application, in the
common, normally-accepted, non-SGML meaning of the term, as is HyMinder,
as is Adept, as is Microsoft Word, as is SoftQuad Panorama.  Only some of
these are also SGML Applications.

So an application can preserve a distinction between data, data format
and implementation if it wants.  I assume that Eliot meant data format
rather than data, or he really _is_ out to lunch.

Eliot, I stand by my claim that too much HyTime rots the brain :-)
