You can also use a shorthand notation:
<book category="enumeration('children','adult','unknown') [0..1]">
<title> string() </title>
<description> string() [0..1] </description>
<author> string() </author>
<ISBNSet> [0..1]
<ISBN> numeric(8,15) [1..*] </IBSN>
</IBSN>
<price> decimal(4,2) </price>
</book>
<bookSet> [0..1]
<book> ref [1..*] </book>
</bookSet>
or even use a compact notation:
description:string
ISBN: /\d{13}/
book
@category:enumeration ?
title:string
author:string
description:description ?
ISBNSet ?
^ISBN
price:decimal(4,2)
(Getting close to RNC, admittedly)

I recently put together a schema language for newbies that aims to be simple. The idea was that an example of your XML data could be your schema. Chances are that alone wouldn't be rich enough, so you can then add annotations to it to better describe what you want. For that reason I've called it "Annotated XML Example" or AXE.
