I have a quite basic question, but I could find a solution.

How can I define in XMLSchema that an element should provide a text
value? When I validate the following XML with the XSD I get no error,
because the empty string seems to be a valid string as well.

	<a></a> <-- if a is <a> is included it should have an xs:string
text node
	<a></a> <-- a second <a> is also not allowed

XSD fragment:
	<xs:element name="root">
			<xs:choice maxOccur="1"> <-- why does it not
invalidate the second <a>?
				<xs:element name="foo" type="xs:string"
minOccurs="1" />

Thanks for replies,
