I was able to figure out my problem after scratching my head for a while
followed by some trial and error.
Here is the binding that appears to work (with some other changes due to
some further updates I made):
<binding>
<mapping class="a.b.AbstractMessage" abstract="true" ordered="true">
<structure name="CommonInfo" field="header" ordered="false"
flexible="true">
<value name="TransactionID" field="transactionId"/>
</structure>
</mapping>
<mapping name="myXML" class="a.b.c.Foo" ordered="true"
extends="a.b.AbstractMessage">
<structure map-as="a.b.AbstractMessage"/>
</mapping>
</binding>
It doesn't really look like I did anything different, but perhaps the bug
about optional structures "not being handles consistently unless they have
an associated property value" bit me.
