General question (not yet a JIRA issue)

Greetings,

When looking at TYPE I read:

> Portable documents *shall not* depend on receiving a value of 4.
>
Since TYPE returns a number indicating a value type, I am not real sure 
what it means to "not depend on receiving a value of 4." ???

BTW, 4 is logical.

So a portable document could accept some other number for logical type? 
Or doesn't recognize logical type? Or if it does, then it isn't a 
portable document?

Not sure how to enter this as a JIRA issue as it isn't clear what was 
meant.

Hope everyone is looking forward to a great weekend!

Patrick
