Issue 14536: Stereotyped Constraints in UML (uml2-rtf)
Source: Alion Science and Technology (Mr. Jim Logan, jllogan+omg(at)gmail.com)
Nature: Uncategorized Issue
Severity: 
Summary: In the UML 2.2 spec (ptc/2008-05-05), there is no way to show that a constraint on a class has a stereotype or stereotype tags. I would like to see something with nested braces. For example, { <<stereotype>> constraint1: body {tag1=value, tag2=value} }.

I recommend changing the notation from this:

A Constraint is shown as a text string in braces ({}) according to the following BNF:

<constraint> ::= '{' [ <name> ':' ] <Boolean-expression> '}'


to this:

A Constraint is shown as a text string in braces ({}) according to the following BNF:

<constraint> ::= '{' [ <stereotypes> ] [ <name>  ':' ] <Boolean-expression> [ '{' <valuestring> '}' ] '}'

The <stereotypes> and <valuestring> use the presentation options described in 18.3.8 (Stereotype).
