Re: Including content modes in 4.1

As I understand the specific issue that Lisa raises, there are two types of 
Hebrew, one with vowel marks and one without.  If someone is presented 
Hebrew without vowel marks, they might not be able to read it (either 
through a processing disability of their own or their user 
agent's).  Therefore, we want to suggest using Hebrew with vowel marks.

One way to generalize this is to say
"use fonts, languages, API's, and protocols..."
"use character encodings, languages, API's, and protocols..."
"use character sets, languages, API's, and protocols..."

This is based on my understanding of these documents:

"content mode" seems too general a term and one that I do not see used in 
the Internationalization documentation on the W3C site. 

I also think that we might be able to include this as an example of 
selecting which (markup) language to use - assuming that with SVG and 
future support of styling languages one could select or create a Hebrew 
font with vowel marks over one without.

Regardless, this is a good example to add as part of the rationalization.
