Re:  Micro XSD for Micro XML?
alternatives would be indicated via the pipe character: "|"

    ISBNSet ?
          ^ISBN +
    ^priceUS |^priceUK

I'm trying to write this while debugging some XSD code for use in JAXB, so I apologize for the sporadic corrections. I should concentrate on my XSDs (bleeurgh).

Let's try that again:

&descript: string
ISBN: /\d{13}/
priceUS: /\$\d+\.d{2}/
priceUK: /£\d+\.d{2}/

    @category:enumeration ?
    description:descript ?
    ISBNSet ?
          ^ISBN +

    ^book *

/../ indicates a regular expression
? indicates an optional element
+ indicates 1 or more items
* indicates 0 or more items
^ is a reference to a previously defined element.
& is a complex type
a:b indicates that element a is of type b

Similar notation could handle groups

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>
<price> decimal(4,2) </price>

<bookSet> [0..1]
      <book> ref [1..*] </book>

or even use a compact notation:

ISBN: /\d{13}/

    @category:enumeration ?
    description:description ?
    ISBNSet ?

(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.

Vaclav Trojan has a similar schema-by-annotated-example specification in the form of XDefinition:

see http://www.syntea.cz/xdweb/userdoc/XMLPrague2009_en.pdf

<book category="optional enumeration('children','adult','unknown')">
<title> required string() </title>
<author> required string() </author>
<IBSN> optional numeric(8,15) </IBSN>
<price> required decimal(4,2) </price>
