The second line of the following does not parse:
The reason for this is that the ConnectionUsage production uses UsageDeclaration (see subclause 22.214.171.124.1):
However, UsageDeclaration does not include ValuePart, which provides the syntax for feature values (see 126.96.36.199.2):
On the other hand, 7.13.2 states that “A connection definition or usage (that is not of a more specialized kind) is declared as a kind of occurrence definition or usage (see 7.9.2), using the kind keyword connection”, and an occurrence declaration (in the informal sense) can, in general, include a feature value, so it would be expected to be allowable for a connection, too.
Note that this is also a problem for interactions, but not for messages or flow connections, which explicitly allow a ValuePart (see 188.8.131.52.4):
