Valid test resources:

Contain a daptm:represents attribute on a <tt>, <body> or <div> element such that there is a non-empty computed value for daptm:represents on every <div> element that does not have any <div> element children, where the attribute value is non-empty and is a valid <content-descriptor> value AND
- the computed value of daptm:represents is a valid content descriptor sub-type of one of the values in the daptm:scriptRepresents attribute on the <tt> element

Should test for extension content-descriptor values beginning x- as well as those in the Registry.

Expect >=1 valid test resource, since many valid combinations can exist in the same resource.

Invalid test resources:

Contain no daptm:represents attribute on a <tt>, <body> or <div> element such that there is an empty computed value for daptm:represents on at least one <div> element that does not have any <div> element children OR
Contain a daptm:represents attribute on a <tt>, <body> or <div> element that is not a valid content descriptor sub-type of one of the values in the daptm:scriptRepresents attribute on the <tt> element OR
Contain a daptm:represents attribute on a <tt>, <body> or <div> element whose value is not a valid <content-descriptor>

Expect >=1 invalid test resource, since many invalid combinations can exist in the same resource.
