What undocumented functionality?
<cfproperty> serves just two purposes:
1. If you write a web service that returns a complex type, you can use
a CFC that 'declares' the public keys of that type using <cfproperty>.
2. <cfproperty> adds property metadata to the CFC metadata (this is
really just a side-effect - the metadata is intended to support #1).
An example of #1 is returning a structure containing a name and an age:
person.cfc:
<cfcomponent>
<cfproperty name="name" type="string"/>
<cfproperty name="age" type="numeric"/>
</cfcomponent>
Then your web service method (in another CFC):
<cffunction name="getPerson" returntype="person" access="remote" output="false">
...
<cfset var result = createObject("component", "person") />
...
<cfset result.name = "Sean" />
<cfset result.age = 43 />
...
<cfreturn result />
</cffunction>
The metadata enables CF to generate the appropriate WSDL so that other
servers can unmarshall the structured return type object.
