Another point on wording, should we say "The first number" or "The first digit" ?

The risk of ambiguity is very low, but we're saying that the "HTTP version
number" is composed of two digits, then when we say "the first number", it
might be possible to read it as the HTTP version number composed from the
two digits. I think that talking only about digits removes any doubt :

    The HTTP version number consists of two decimal digits separated by a "." 
    (period or decimal point).  The first digit ("major version") indicates the 
    HTTP messaging syntax, whereas the second digit ("minor version") indicates 
    the highest minor version to which the sender is at least conditionally 
    compliant and able to understand for future communication.

Best regs,
