The following recent change to css2/syndata:
-ruleset : selector? '{' S* declaration? [ ';' S* declaration? ]* '}' S*;
+ruleset : selector? '{' S* declaration-list '}' S*;
+declaration-list: declaration [ ';' S* declaration-list ]?
+ | at-rule declaration-list
+ | /* empty */;
...
declaration : property S* ':' S* value;
has the effect that leading semicolons and consecutive semicolons
within a ruleset block no longer conform to the core grammar.
Is this intentional? It seems a bit late to be changing the
conformance of so common an occurrence (e.g. due to commenting
out a declaration), even if error recovery means it doesn't
make a difference to web browser behaviour. (It might also
require re-examining css2 statement of error recovery behaviour
for this case.)
