Actually, with proper Unicode libraries it would be reasonable easy  
to handle any base-10 integers.

Such a scheme could be extended to numbers with a fractional decimal  
part if the decimal separator was given in an attribute explicitly  
(defaulting to "."). Thousand separators could be dealt with by  
skipping certain character classes.

It is reasonable to expect desktop and server software to have access  
to the Unicode database (e.g. by bundling ICU if there's isn't a  
proper platform API). However, JScript-based emulation layers on top  
IE and mobile software may not have access to the Unicode database.
