Routine Description:

    Returns TRUE if the input string is a hex string of a
    desired length.

Arguments:

    Name - NULL or NULL terminated hexadecimal string
    NameLength - meaningfull only if Name is provided
    MustHaveInput - TRUE if null Name input is not allowed

Return Value:
    TRUE if success, FALSE otherwise

Routine Description:

    Returns TRUE if Name is valid.  When Name is not NULL,

Arguments:

    Name - NULL or NULL terminated RPL path string
    MaxNameLength - meaningfull only if Name is provided
    MustHaveInput - TRUE if null Name input is not allowed

Return Value:
    TRUE if success, FALSE otherwise
