Since the project i'm working on "xs:override implementation" is not
currently mentioned under GSoc JIRAs can you please add it to the above list
as well .
Here is the description of the JIRA.
*
* *Summary* : Implementing XMLSchema1.1  overriding component definitions
(<xs:override>)
*Component/s:* XML Schema 1.1
Structures<https://issues.apache.org/jira/browse/XERCESJ/component/12312420>
*Affects Version/s:* 2.9.1
*Labels:* 
gsoc<https://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&customfield_12310260=gsoc>
*Description :

*XML schema specification version 1.1 [1] specifies syntax and semantics of
“Overriding component definitions<override>”[2] or xs:override , under
“Schemas and Namespaces: Access and Composition” . The new component
definition is a powerful addition to the XML schema composition
framework  ,which
tries to mitigate some of the constraints present in similar constructs such
as xs:redefine or <redefine> schema component. The <redefine> construct
defined in “Including modified component definitions (<redefine>)
<http://www.w3.org/TR/xmlschema11-1/#modify-schema>“[3] on XMLSchema
specification is useful in schema evolution and versioning. It can be used
only when there exists some restriction or extension relation between the
old component and the new redefined component. But there are occasions when
the schema author simply wants to replace old components with new ones
without any constraint. Also, existing XSD processors have implemented
conflicting and non-interoperable interpretations of
<redefine><http://www.w3.org/TR/xmlschema11-1/#element-redefine>.
The implementation of  new construct
<override><http://www.w3.org/TR/xmlschema11-1/#element-override>on
Xerces XMLSchema processor ,would avoid these bottlenecks and allow
unconstrained replacement as and when needed by the schema author. Possible
Mentors:* Khaled Noaman*
