Urg. Why so wordy? Just do:
0 TEXTURE <position vector> <orientation matrix> <filename.type> [START
<standard ldraw commands go here>
0 TEXTURE END]
The <position vector> and <orientation matrix> parameters are identical to
the parameters on the standard subfile command (linetype 1).
The entire START ... 0 TEXTURE END segment is optional. If someone is
making a custom file, they don't have to include any more code than is
necessary.

That would work, but would require the use of a subfile for the pattern.
Which isn't the end of the world.
0 TEXTURE <filename.type> [START]
1 16 <position vector> <orientation matrix> <filename.dat>
0 TEXTURE END
An advantage of this approach is that existing tools (such as LDAO) can
still be used to edit (rotate, scale, inline) this code.
Is there any reason that both syntaxes couldn't be supported?
BTW, none of this stuff will ever make it into the LDraw/LCAD parts
library, in the library's current form. At some point in the future, I
hope we advance enough to require a new library, with parts that are no
longer compatible with the old LDraw/DAT standard. But we aren't there
yet.
The main reason that this won't make it to the library is *not* the
meta-commands. It is because we'd have to carry the extra image files in
the library. The current (unwritten) spec does not allow non-DAT files to
exist in either the ldraw\p\ or ldraw\parts\ subdirectory trees.
