Are you saying that a schema should define or reference xml:lang and 
xml:id attributes? Or that the instance documents should use those 
attributes as much as possible?

As for the DOM getElementById making use of xml:id attributes in an 
instance document, a test with http://jsfiddle.net/ady5P/ shows that 
only Opera supports that, Firefox, Chrome, IE 9, Safari don't do that.

As for your pattern example <xs:pattern value="[&#1;-&#127;]*" />, the 
character &#1; is not allowed in XML 1.0 documents which most schemas 
likely are these days.
