XProc Next Community Group Proposed

As decided at the XProc Workshop in London on June 12 (see https://github.com/xproc/Workshop-2017-06/wiki/Minutes), I have now proposed a new community group for XProc, XProc Next. The description is as follows:

Create a place for gathering requirements from existing and potential users of XProc, research in this area, and for supporting and writing the community-driven effort to define an XProc 3.0 specification (formerly 1.1) .

Once the proposal has been reviewed by the W3C staff, the proposed group will appear at https://www.w3.org/community/groups/proposed/.
