Alfresco Share: how to use evaluator="aspect" to check for (parent) aspect

Question

I have one aspect which is the parent aspect of two other aspects.

<aspect name="my:parentAspect">
</aspect> 

<aspect name="my:subAspect1">
    <parent>my:parentAspect</parent>
</aspect>

<aspect name="my:subAspect2">
    <parent>my:parentAspect</parent>
</aspect>

Now I want to use the "aspect"-evaluator in my share-config-custom to apply some customization if a node directly has the aspect "my:parentAspect" or if the node has an aspect that has inherited from "my:parentAspect" by having it as a parent.

<config evaluator="aspect" condition="my:subAspect1">...</config>
<config evaluator="aspect" condition="my:subAspect2">...</config>

works, but I would prefer to use

<config evaluator="aspect" condition="my:parentAspect">...</config>

because the configs for each subAspect are actually all the same.
However, this does not work for nodes that don't have the my:parentAspect directly attached bu only inheriting the aspect.

What's the best practice to check for an aspect regardless whether it's directly applied or inherited somewhere down the hierarchy?

regarding your own comments: don't mix form configs & doclib configs!

org.alfresco.web.config.forms.AspectEvaluator is the Evaluator for form configs like

<config evaluator="aspect" condition="my:parentAspect">...</config>

org.alfresco.web.evaluator.HasAspectEvaluator.java is used for aspect-related evaluator within

<config evaluator="string-compare" condition="DocumentLibrary">

e.g. for indicators, metadata-templates etc. So, org.alfresco.web.config.forms.AspectEvaluator is the one here. It's a subclass of org.alfresco.web.config.forms.NodeMetadataBasedEvaluator that uses the api/metadata Webscript to get the Metadata of the given node:

/api/metadata?nodeRef=" + nodeString + "&shortQNames=true"

This webscript uses org.alfresco.repo.jscript.ScriptNode.toJson() which only includes directly attached aspects.That could be your starting point for a custom Evalutor.
