about the "numeric" attribute:
By definition, two identifiers would only need to be compared for equality. Since each identifier is a string of symbols, equality can be assumed if each symbol matches that of another identifier in the same place.
Some identifier systems, however, use values that can be represesented in different encodings. Numbers retain their value if they are converted between different number systems (e.g. Roman or Arabic numerals), or between number bases (e.g. decimal, octal, binary, hexadecimal, etc.). Moreover, numbers can be represented with groups of digits using different separators where the meaning of the separator can differ between cultures (e.g. 1,000 means one thousand in the anglo-american world and exactly one in Germany).
