This is a series of test cases intended for tools which extract titles from web resources; they exercise respecting the Content-Type and XML namespaces.
- Test #1: plain text file; there is no formal definition by which this resource has a title.
- Test #2: RDF document including one random element and one HTML-title element, which by RDF interpretation is not a title. [TODO: check with RDF validator]
- Test #3: HTML document containing non-title in a comment.
- Test #4: XHTML using namespaces.
