New edition of the XML FAQ

The XML FAQ at http://xml.silmaril.ie/ has been revised and updated, and
regenerated in a completely new format using a responsive design that
should work on most mobile devices. Some obsolete questions were
deleted, and several new ones added, and the search function was improved.

All bugs, errors, and suggestions or (better) contributions for new
material should be reported to the editor at xmlfaq@xxxxxxxxxxx

Please feel free to circulate this to your colleagues, clients,
students, etc.
