Two Relax NG compact questions

[Manfred Lotz]

Hi there,
I've got two questions.

1. Using Relax NG compact I want to define an element which I don't
want to be empty.

I did this:

element library { xsd:string { minLength = "1" } }

Question: Could this be done in an easier way?


2. In an element definition I could use either string or text.
Example:

element book { text }

element book { string }

Question: What is the difference between string and text in this
context?
