Hi Mark,

The following schema will do what you need:

<?xml version="1.0" encoding="utf-8" ?>

<xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd"

elementFormDefault="qualified"

xmlns="http://tempuri.org/XMLSchema.xsd"

xmlns:mstns="http://tempuri.org/XMLSchema.xsd"

xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:simpleType name="my30charsType">

<xs:restriction base="xs:string">

<xs:maxLength value="30"/>

</xs:restriction>

</xs:simpleType>

<xs:element name="myElem">

<xs:complexType>

<xs:simpleContent>

<xs:extension base="my30charsType">

<xs:attribute name="myAttrib" type="my30charsType"/>

</xs:extension>

</xs:simpleContent>

</xs:complexType>

</xs:element>

</xs:schema>

Well, despite reading an excellent article on ComplexTypes,
I am unsure on the quickest way to express the following
<myElem myAttrib="noMoreThan30chars">
No More than 30 chars
</myElem>
Both on the string are SimpleContent, right?

Thanks, Mark

BTW the article is

Thanks, originally thinking about defining them "in-line", but your way is
cleaner.

If would have been nice if Xml Schema had defined a global types section to
keep root elements and types separate.
<schema>
<rootElements>
<foo....
</rootElements>

<globalTypes>
<fooType....
</globalTypes>
</schema>

Ciao
Mark
