Hi,
Currently, the grammar allows the following:
#-2bar { color: red }
#-2bar is recognized as a HASH usable as a selector
<<
simple_selector
: element_name [ HASH | class | attrib | pseudo ]*
| [ HASH | class | attrib | pseudo ]+
;
"#"{name} {return HASH;}
name {nmchar}+
nmchar [_a-z0-9-]|{nonascii}|{escape}
>>
But the text says:
<<
In CSS, identifiers (including element names, classes, and IDs in
selectors) can contain only the characters [a-z0-9] and ISO 10646
characters
U+00A1 and higher, plus the hyphen (-) and the underscore (_); they cannot
start with a digit, or a hyphen followed by a digit. Identifiers can also
contain escaped characters and any ISO 10646 character as a numeric code
(see next item). For instance, the identifier "B&W?" may be written as
"B\&W\?" or "B\26 W\3F".
>>
So the text and the grammar are not synchronized.
Shouldn't selector use a production capturing those requirements,
(something along the line of HASHIDENT = '#' IDENT) instead of HASH?
Cheers,
