           Summary: Refactor the entity parser to handle new entities
                    needed by MathML 3
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: MathML
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sausset at gmail.com


The w3c published a new recommendation for entity names: http://www.w3.org/TR/xml-entity-names/.
MathML 3 should implement all these entities and HTML 5 only a subset.
However, the actual entity parser cannot handle these new entities.

Thus, the entity parser should be rewritten in the following way (see discussion on the mailing list):
- use a prefix tree instead of a hash table (faster and handle entity names as long as wanted)
- handle entities associated to combined Unicode characters
- solve the conflict with XHTML 1.0 about ⟩ and ⟨ (see w3c webpage above)
