 <h1>Xerces-2 Schema beta</h1>

 <p><b>Features:</b>
 <ul>
 <li>Full xerces-1 schema support
 <li>New datatype validator design
 <li>PSVI support
 <li>Grammar caching
 <li>Misc. DOM L3 features
 </ul>
 <p><b>Target DCUT (code complete) date: </b> Nov. 30
 <p><b>Target release date:</b> late December

 <p><b>Open Issues:</b>
 <ul>
 <li>How do we pass PSVI info thru XNI?  (see Andy Clark's proposal)
 <li>Do we need to change our content model representation to include model group components?
 <li>How do we expose the PSVI info to the application?
 </ul>

 <p><b>Clean-up work.   Needs volunteers. </b>
 <ul>
 <li>Use reference comparison for schema element names in traversers.   Needs some investigative work.
 <li>Error messages:  get rid of all calls to reportGenericSchemaError and ensure there are appropriate messages in the properties file.
 <li>General performance work:  revisit use of Hashtable, Vector, string concat, QName lookup, etc.
 <li>Complete work in the decl pool, and change the traversers to use it.
 <li>Revisit our validation options and their semantics.
 <li>Potentially revisit ENTITY validation - See Schema Rec Issue R-66.
 </ul>

 <p><b>Features to be implemented if time permits</b>
 <ul>
 <li>Improved simple content model support
 <li>Support for content models containing large minOccurs/maxOccurs values
 <li>Improved error detection for XML Schema errors:  try to emit errors using line numbers from the Schema itself, and not the instance.
 </ul>
