I know one shouldn't look a gift horse in the mouth, but ... there seems
to be considerable confusion about the version numbers in the recent
batch (16 Jan) of Adobe standards available from their file server:

 The new struct.ps announces itself as Version 2.1, and the Examples
 at the end start "%!PS-Adobe-2.1". But in other places it talks as
 though the version number were still 2.0 (e.g. sections 4.3, 5, and
 5.1 talks explicitly about using the string "%!PS-Adobe-2.0" to start
 the document).

 The new PPDformat.ps calls itself Version 3.0 initially. Then it has
 a `NOTE' which makes one think it might be 2.1. Then, to be ultimately
 confusing, it has an example PostScript document (on page 4) starting
 "%!PS-Adobe-3.0", as though there were a version 3.0 of the Document
 Structuring Conventions as well.

Can anyone from Adobe (or anyone at all) say what the situation about
version numbers really is?

Here is something else that might cause unseemly mirth. All the new
documents have been prepared with a system that generates PostScript
which has a spurious extra %%Page containing code that never generates
anything. Thus when the %%Pages: comment claims that it is going to
generate N pages, only N-1 are actually printed.
