Some script mixing *within* a label should be restricted as it is a 
security risk. Script mixing across a FQDN or between local part and 
host seem to be rather likely scenarios instead.

For certain scripts, ASCII admixture (just ASCII, not all of Latin) 
would be common practice in the writing system and it may be common 
enough/benign enough to allow it.

However, you might also want to address European digits for those 
scripts where native digits exist and are widely / predominantly used, 
vs. scripts where the native digits are more of historic/cultural 
interest. (In Arabic you have both, depending on the region).

Mixing digit sets in the same label should be a no-no and indicated 
something's not well-formed.

My naive interpretation had to do with things like tables or data 
records where the purpose of a particular field would be a URL.
