Hi Dan, all:

For a quick fix, you could take a few lines from the GoodRelations extension proposal. Of course, one would have to replace the old schema:domain/range properties by the new ones, so it would be:

"Syntax for Extension Proposals

schema.org can process extension proposals with a lot less effort if they are submitted in an RDFa-syntax following the syntax shown below:""

Example of a new type:

<!-- additional class from http://purl.org/goodrelations/ -->
<div typeof="rdfs:Class" about="http://schema.org/QuantitativeValue">
	<span class="h" property="rdfs:label">QuantitativeValue</span>
	<span property="rdfs:comment"> A point value or interval for product characteristics and other purposes.</span>
	<span>Subclass of: <a property="rdfs:subClassOf" href="http://schema.org/StructuredValue">StructuredValue</a></span>
	<span>Source:  <a property="dc:source" href="http://www.w3.org/wiki/WebSchemas/SchemaDotOrgSources#source_GoodRelationsClass">GoodRelations</a></span>

<!-- additional property from http://purl.org/goodrelations/ -->
<div typeof="rdf:Property" about="http://schema.org/valueReference">
	<span class="h" property="rdfs:label">valueReference</span>
	<span property="rdfs:comment">A pointer to a secondary value that provides additional information on the original value, e.g. a reference temperature.</span>
	<span>Domain: <a property="http://schema.org/domainIncludes" href="http://schema.org/QualitativeValue">http://schema.org/QualitativeValue</a></span>
	<span>Domain: <a property="http://schema.org/domainIncludes" href="http://schema.org/QuantitativeValue">http://schema.org/QuantitativeValue</a></span>
	<span>Range: <a property="http://schema.org/rangeIncludes" href="http://schema.org/StructuredValue">StructuredValue</a></span>
	<span>Range: <a property="http://schema.org/rangeIncludes" href="http://schema.org/Enumeration">Enumeration</a></span>
