Proposed Schema Updated

Acting on many helpful comments, I've made some improvements to the future 2.0 schema, including the addition of "professional summary" and "extendedPersonalInfo" elements, a switch from attributes to elements, increasing the hierarchy (makes formatting simpler), and added multiple periods for roles. The schema is still located at http://tinyurl.com/3xp3d.

A big thank you to all who have commented, and thanks in advance to those who would like to improve this version.
