Don't know if it's relevant, but I've been reading the portion of the WMS
spec concerning
nested layers just a few days ago.
When nesting layers there are two cases:
- the parent layer has a Title, but not a Name. This is known as
"containing category",
  it helps categorizing the layers but cannot be called directly
- the parent layer has a Name, in such case it is callable and when
requested
  it should build a map with all the children

So, by my understanding of the spec, if your parent Layer does not have a
Name
ArcGis is right in not calling it, but if it has a Name, then it's a bug in
ArcGis.

Hope this helps

Cheers
Andrea
