Hi,
This comment from the Gen-ART review deserves it's own thread.
gen-art> - section 7.6.4
gen-art>
gen-art> The default value MUST NOT be marked with an "if-feature" statement.
gen-art>
[...]
gen-art> But it's not clear what the whole set of situations is that should be
gen-art> forbidden. For instance, this should work:
gen-art>
gen-art> typedef xyz {
gen-art> type enumeration {
gen-art> enum blue { if-feature blue; }
gen-art> ...
gen-art> }
gen-art> }
gen-art>
gen-art> leaf color {
gen-art> if-feature blue;
gen-art> type xyz;
gen-art> default blue;
gen-art> }
gen-art>
gen-art> Whereas this won't:
gen-art>
gen-art> typedef xyz {
gen-art> type enumeration {
gen-art> enum blue { if-feature blue; }
gen-art> ...
gen-art> }
gen-art> }
gen-art>
gen-art> leaf color {
gen-art> // No if-feature here.
gen-art> type xyz;
gen-art> default blue;
gen-art> }
gen-art>
gen-art> Is this rule only meant to cover the situation where the leaf's type
gen-art> is an "in-line" enum and the particular enum value has an if-feature?
mbj> Good point. Yes, the first example should be valid. Another valid
mbj> example would be:
mbj>
mbj> container colors {
mbj> if-feature blue;
mbj> leaf color {
mbj> type xyz;
mbj> default blue;
mbj> }
mbj> }
mbj>
mbj> Maybe:
mbj>
mbj> OLD:
mbj>
mbj> The definition of the default value MUST NOT be marked with an
mbj> "if-feature" statement.
mbj>
mbj> NEW:
mbj>
mbj> If the definition of the default value is conditional based on one or
mbj> more features (see ^if-feature^), then the leaf node MUST
mbj> also be conditional based on at least the same set of features.
mbj>
mbj> (modelled after the text in 9.9)
Does anyone have comments on this proposal?
