[dsdl-discuss] Re: Does Part 7 need built-in definitions for IANA sets?

I might be biased, since I care DBCS but do not care SBCS. However,
if IANA charsets are useful only for SBCS, I do not see big advantages
in using them.

After all, SBCS can represent at most 256 characters. A block escape
"IsBasicLatin" already covers 128 and another block escape "IsLatin-1Supplement"
also covers 128. By combining these blocks, code points, code ragnes, the union
operator (i.e., posCharGroup) and the difference operator (i.e., charClassSub),
it is very easy to define any SBCS.

This sounds nice to me.

Thanks. I will then create a CD based on that version.
