Re: explanation for putting the last saved date in. Your explanation
certainly makes practical sense and I was being a purist.

As more tools are developed perhaps this needs serious thought, however,
as I suspect this kind of information will become crucial (especially
given the kind of havoc Joe's Universal TEI editor seemed to cause in
your fantasy example). Early on in this discussion, people argued
against putting tools in the revision statement because there was no
intellectual responsibility involved. But the more sophisticated the
tool the more important the revision record, I'd think.

Certainly your solution is a good interim one. But ultimately, I think
we are going to have to think more about how tools are like and not like

My mistake, I meant langusage:

    <language id="ENG">English, Present Day (Canadian Standard Spelling)</language>

This is a model for what I think you are doing because it provides
metadata about something that can be referred to elsewhere (I suppose it
might be a specialised kind of FS). Of course creationApp is not quite
the same thing, because you presumably wouldn't use it in the way you
used to use tei:@lang (i.e. marking individual elements as made by a
specific tool in the main text (though I suppose you could). But it
would, for example, allow you to identify those tagsDecl elements imt is
adding and removing to the header (or to harp on a point, information
about revisions introduced by the tool ;-) ) in the same way in P4 you
could indicate that a specific element contained text in Old High
German, e.g.:

<tagsDecl tool="imt" ... >

Obviously in your case, you are adding more children, but the principle
seems the same to me.
