So you would propose [\c]* (removing the negation from ^\s)? (Allows all 
valid XML name characters)

Not sure what you saying here in terms of changing the regex syntax, 
proposed syntax follows, can you edit to illustrate?

<xs:pattern 
value="(([\c]*\.){0,6}([\c]*))(@((cp:(\d*)(\+(\d*))?\((.*)\))|((x-(\c*):)(.*)\((.*)\))))?((-(([\c]*\.){0,6}([\c]*)))?|(-(([\c]*\.){0,6}([\c]*)))(@((char:(\d*)\+(\d*)\((.*)\))|((x-(\c*):)(.*)\((.*)\))))?)?"/>
