Re: output/label/help/hint/alert unification

I made these changes:

   * moved @class and @xml:lang to Common
     https://www.w3.org/community/xformsusers/wiki/XForms_2.0#Common_Attributes

   * added a normative reference to xml:lang
     https://www.w3.org/community/xformsusers/wiki/XForms_2.0#ref-xml-lang

   * Created a Navigation attribute set containing @navindex and  
@accesskey, and added it to Control Common
     https://www.w3.org/community/xformsusers/wiki/XForms_2.0#Common_attribute_and_content_sets

Please check.
