Latest CSS 2.1 spec seems to suggest that identifiers can start with a hyphen
(-) followed by an alphabetic character [A-Za-z].

Also,
CSS 2.1, section G.3 Comparison of tokenization in CSS 2.1 and CSS1
http://www.w3.org/TR/CSS21/grammar.html#tokenizer-diffs
says 
{
In CSS1, a class name could start with a digit (".55ft")
}
which is not true.

Finally, HTML 4.01 claims that
{
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by
any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons
(":"), and periods (".").
}
