Detailed Description

Parser for attributes::

    attributes { id = "foo", class = "bar baz",
                key1 = "val1", key2 = "val2" }

Adapted from:
https://github.com/jgm/djot/blob/fae7364b86bfce69bc6d5b5eede1f5196d845fd6/djot/attributes.lua#L1

syntax:

attributes <- '{' whitespace* attribute (whitespace attribute)* whitespace* '}'
attribute <- identifier | class | keyval
identifier <- '#' name
class <- '.' name
name <- (nonspace, nonpunctuation other than ':', '_', '-')+
keyval <- key '=' val
key <- (ASCII_ALPHANUM | ':' | '_' | '-')+
val <- bareval | quotedval
bareval <- (ASCII_ALPHANUM | ':' | '_' | '-')+
quotedval <- '"' ([^"] | '\"') '"'
