OK.
Thanks for the encouraging words, Mike.
I also put some suggestions on the wiki:

[DFDL-WG] This week's DFDL WG meeting
I will be unable to attend this week's call.
Martin said he also would be unable to attend.
However, Simon sent a marked up document last week (forwarded in
this email) and the comments he made might be discussed this week if
there is a quorum. E.g., he suggests reformulating the properties we use
for length along the lines originally suggested by Kris Rose, i.e,
eliminate the separate lengthUnits property to reduce coupling. Somehow
Simon's version seems simpler though.

DFDL specification comments
Good afternoon.
As long promised, I've read the specification and embedded some
comments and suggested corrections with 'Track changes' switched on.
I have some observations that don't fit well in those little
yellow boxes, so I hope to air them on the wiki.
I see significant opportunities for simplifying the language and
its specification in the area would call 'composability' (encompassing
'Kernel DFDL' and 'Layers'). In short: find a general way to define
complex structures as groups of simple fields.
I've already offered to try to find an alternative technique for
specifying parser semantics, but haven't made much progress with that
yet.
Some ideas occurred to me as I read about defaults, null values
and so on. It's a smaller topic and maybe an easier starting point, so I
created a wiki page.
Like everyone, I've not much time to devote to this interesting
and worthwhile project. My contributions may seem sketchy, terse or
ragged, but they're well meant.
More later,
Simon
