How do i create an RDFa definition for something like "textNode HTMLElement textNode"?

Question

Im trying to create some custom blocks for a CMS interface based on the symfony-cmf. In order for these blocks to be edited inline with createphp/hallo i need to create RDFa mappings for them.

The basic example for an included block is something like the following:

<type
        xmlns:sioc="http://rdfs.org/sioc/ns#"
        xmlns:dcterms="http://purl.org/dc/terms/"
        xmlns:skos="http://www.w3.org/2004/02/skos/core#"
        typeof="sioc:Post"
        >
    <attribute key="class" value="articleContainer span3"/>
    <children>
        <property property="dcterms:title" identifier="title" tag-name="h2"/>
        <property property="sioc:content" identifier="content" />
    </children>
</type>

Which would yield something like this:

<h2>The title input</h2>
<p>the content, however i beleive the actual &lt;p&gt; tag is applied by the editor</p>

Thats all well and good... What Im having a hard time figuring out how to define this mapping for a resource that will be something like this:

<h1>Text string with <strong>emphasized phrase</strong> in the middle</h1>

I could probably just use the sioc:content type and then rely on the user to "bold" the emphasized phrase in the editor but i would rather have it be edited explicitly.

Is there a way to do this? Also if anyone could point me towards solid RDFa tutorials that would be great. My google-fu is usually strong but all i can seem to find are the actual spec, and a bunch of posts about seemingly unrelated usages.

The idea of the RDFa mapping is to specify which properties of the document you want to render with which tags. Actual content typically is WYSIWYG. I guess RDFa being quite complex it would support inline-nested information like what you are asking for. But the midgard/createphp component which reads this XML configuration to generate the right data does not support nested content. I am not sure if create.js would support it, but i think not.

Note that you can map children and output whole content hierarchies. But that would not handle your emphasised fragment.
