[flex_next] asdoc xslt files generate warning when a tag is followed by colon (:)

Steps to reproduce:
1. Add the following to an action script class
/**
*

• @param id: the id of the control
• @return: the control object
  *
  */
  public function foo(id:String):Object { return null;}

2. Run asdoc on the class

Actual Results:
generates warnings like:

Error on line 4 column 65 of _Global_.xml:
SXXP0003: Error reported by XML parser: Element or attribute do not match QName
production: QName::=(NCName':')?NCName.
Recoverable error on line 25 of merge_dita_xml.xslt:
FODC0002: org.xml.sax.SAXParseException: Element or attribute do not match QName
production: QName::=(NCName':')?NCName.
Error on line 4 column 65 of _Global_.xml:

Recoverable error on line 27 of Classes.xslt:

Error on line 4 column 65 of _Global_.xml:
SXXP0003: Error reported by XML parser: Element or attribute do not match QName
production: QName::=(NCName':')?NCName.

Expected Results:
No cryptic warnings. Should generate an easy to understand (actionable) warning.

Workaround (if any):
remove : after return.
