DTV — Date Time Issue: quotation in OCL of UML symbols that include blanks

During the Architecture Board's review of the final submission, Pete Rivett asserted that the document quotes UML symbols incorrectly when they are referenced in OCL statements. When a UML symbol includes a blank or other special character, the final submission wraps the symbol with double-quote characters. Peter Rivett says that UML has adopted another quoting mechanism. We need to check the UML standard and also what the tools actually support.

The specification is updated to quote OCL symbols using a leading underscore-single-quote character pair and a trailing single-quote character per the latest OCL specification. For example, the symbol 'time interval' is quoted as _'time interval' in OCL.
