Hi Surya,

 

The use of the vertical bar in this grammar rule seems to assume different precedence than in other rules. Although one could add parentheses to the rule to fix the precedence I think your proposal is more transparent. I suggest you make a Mantis item for it.

 

Cheers,

Marq

Subject: Confusion over connect_resolution rule

 

Hi,
I have a confusion on connect_resolution rule. It is defined as:

connect_resolution ::= connect discipline_identifier { , discipline_identifier } resolveto // from A.1.8
discipline_identifier
| exclude
;

As per the position of '|', it seems to me connect_resolution can be resolved to either:
connect discipline_identifier { , discipline_identifier } resolveto discipline_identifier

or

exclude ;

But by the example it seems to me, after resolveto keyword, either discipline_identifier or exclude can be present. So the rule should be rewritten as:
connect_resolution ::= connect discipline_identifier { , discipline_identifier } resolveto discipline_or_exclude ;

discipline_or_exclude ::= discipline_identifier
| exclude

Please correct me if I am wrong.
