Grammar: Use non-ambiguous syntax for xdigit class

While `\p{XDigit}` works, alternate regex engines might interpret it according to UTS #18, which contains more than just the ASCII characters, or not even implement it at all. The YAML spec only contains the ASCII characters, see here: http://yaml.org/spec/1.2/spec.html#id2775468
