				Optional ! is added to Bound due to special values in range constraints, where they have well defined semantics (because special values have concrete encodings)<br />
<br />
In case of length adding ! would complicate the language without obvious advantage and it would be difficult -if not impossible - to explain the semantics of ..!infinity.<br />
<br />
Let's go the opposite way and add the static semantics rule excluding ! for length contraints:<br />
<br />
44.StringLength ::= LengthKeyword &quot;(&quot; SingleExpression [&quot;..&quot; Bound] &quot;)&quot; <br />
<br />
/* STATIC SEMANTICS - StringLength shall only be used with String types or to limit set of and record of.
