One way to do this is to wrap the embedded class in a state, like
this (untested):
<class name="headerview">
...
<attribute name="haschildren"
value="$path{ 'subheader/last()' }"/>
<state apply="${ Number( parent.childcount ) }">
<headerview datapath="subheader" />
</state>
</class>
A slightly less natural way to model this is to collect a list of all the
subheader nodes and then hand it to a replicator. See the opttree
implementation in the incubator directory for an example of this.
