I believe the spec language is unclear here.
It says:
The 'implicit' alignment of complex elements and groups is
the alignment of its child with the greatest alignment.
This could be worded more clearly:
The 'implicit' alignment of complex elements is the alignment
of their model group. The 'implicit' alignment of a model group is the
alignment of its child with the greatest alignment.

The exact semantics of lengthKind='delimited' are a little bit unclear to
me.
Are there situations where we accept end-of-data as a substitute for
finding a delimiter?
Consider this:
<element name="foo" type="xs:string" dfdl:lengthKind="delimited"
dfdl:initiator="[START]" dfdl:terminator="[END]"/>
I think this string should always cause a processing error: "[START] some
data ". That is, the [END] terminator is not present, instead one runs out
of data.
So what exactly are the situations where delimited length kind will not
find a delimiter, hit end-of-data, and be ok with it?
I understand that hitting end-of-data might cause a backtrack for resolving
points of uncertainty, but is there ever a case where running out of data
is accepted as a substitute for finding a delimiter? (I am hoping the
answer here is no, but I am asking because I am not certain.)
