@---+ CustomSearchProposalTwo
Another proposal to fit the CustomSearch requirements.
The ResponseStructure (starting with <structure>) is defined here using a subset of XML Schema with annotated mappings.
Since the XML Schema schema accepts attribute extensions in most elements using:
<xs:anyAttribute namespace="##other" processContents="lax"/>
Then custom requests would not produce invalid XML due to the attribute annotations.
For counting matches and returned records as well as the paging mechanism we need to give a RecordDefinition, in this case also using the annotation technique.
