Reads in part: "The attribute may be evaluated by consumers that do not support script types to select the correct script dependent formatting properties. Consumers that support script types may also evaluate the attribute and overwrite the script type they would evaluate for a certain character."

There are only two types of consumers:

1) Support script types

2) Don't support script types

But the ones that do "may also evaluate the attribute....?

Where is the script type they would evaluate coming from?

Odd that consumers that don't support script types can read this attribute to assist them in picking the correct script dependent formatting properties.

Can anyone suggest what is supposed to happen here?
