1 Purpose

The XML Schema Interest Group is a forum for the discussion of issues relating to the development of a language for defining and documenting XML-based markup languages, including both datatyping and structural constraints analogous to those expressible by XML DTDs. In particular, it serves as a resource for the communication of expert opinions to the XML Schema Working Group.

2 Deliverables

The XML Schema Interest Group does not develop specifications or code and as a body has no concrete deliverables under this charter.

3 Interest Group participation

There are three types of individual participants in the XML Schema Interest Group: Member representatives, Invited Experts, and Team representatives (including the Team Contact). The participation requirement for W3C Member and Team representatives for this Interest Group is subscription to the XML Schema Interest Group mailing list. The participation requirements for Invited Experts for this Interest Group is described in the section "Invited Expert in an Interest Group" in the W3C Process Document.


The initial Chair of the XML Schema Interest Group is C. M. Sperberg-McQueen, W3C.

W3C Team resources

The initial W3C Team contacts for this Working Group are C. M. Sperberg-McQueen and Henry Thompson.

4 Meetings and conferences

The XML Schema Interest Group exists only as an email forum; it does not conduct phone conferences or face-to-face meetings.

5 Communications and confidentiality

The XML Schema Interest Group participants communicate via an archived mailing list, w3c-xml-schema-ig@w3.org. This list is Member-confidential.

To keep debate within useful bounds and to keep the volume of mail within the ability of XML Schema Working Group participants to monitor it, discussions of the XML Schema Interest Group are limited to issues relevant to business currently being conducted by the XML Schema WG. It is the responsibility of the XML Schema Interest Group Chair to moderate discussion as necessary to enforce this rule. In extreme cases, the Chair has the authority to remove XML Schema Interest Group list subscribers if necessary to maintain order on the mailing list.

6 Duration

The expiration date of this charter is 30 June 2006.

7 Patent Disclosures

The XML Schema Interest Group provides an opportunity to share perspectives on schema languages. W3C reminds Interest Group participants of their obligation to comply with patent disclosure obligations as set out in Section 6 of the W3C Patent Policy. While the Interest Group does not produce Recommendation-track documents, when Interest Group participants review Recommendation-track specifications from Working Groups, the patent disclosure obligations do apply.
