<td class="print-category">Description</td>
<td colspan="5" class="print">Component type definitions may contain
declarations of ports, timers, constants, and variables. Constants must
have an initial value, timers and variables may have an initial value.
The only kind of restriction on the expressions for these initial values
is the limitation to 'ConstantExpression' in the BNF for the value of
constants.<br />
<br />
For the default duration of timers and for the initial values of
variables no restriction is given, neither in the next, nor in the BNF.
When arbitrary expressions are allowed, this raises the question when
the expressions are evaluated: at compile time, when 'loading' a module,
when starting a test case, or when creating an instance of a component
type.<br />
<br />
To resolve such questions, it is suggested that any value used in a type
definition, is described by a constant expression (see CR2152). Such
constant expression always evaluate to the same value.<br />
<br />
To each of the clauses for type definitions that contain values<br />
6.1.2.1 Lists of values<br />
6.1.2.2 Ranges<br />
6.2.3 Records and sets of single types<br />
6.2.4 enumerations<br />
6.2.7 Arrays<br />
6.2.10.1 Component types<br />
a restriction should be added that the values have to be defined by
constant expressions.</td>

Some clarifying sentences could be added as it has been done already in

I propose not to add ", see in particular restriction c)"; it is
