I have the following document:
<root xmlns="http://example.com/root";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://example.com/root root.xsd"><foo
xml:space="preserve"> there is leading and trailing whitespace here
</foo></root>
With the following XSD:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://example.com/root";
xmlns="http://example.com/root";>
<xs:import namespace="http://www.w3.org/XML/1998/namespace";
schemaLocation="http://www.w3.org/2001/03/xml.xsd"; />
<!-- Complex types describing all parts of the document -->
<xs:complexType name="fooType">
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute ref="xml:space" fixed="preserve" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
<!-- The actual schema itself -->
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="foo" type="fooType"
minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
When I try to validate by reading in my document and then calling:
NSXMLDocument *document = ...
NSError *error = nil;
[document validateAndReturnError:&error];
I always get the following errors:
Element '{http://example.com}foo', attribute 'space': The attribute
'space' is not allowed.
Element '{http://example.com}foo', attribute 'space': The attribute
'space' is not allowed.
Element '{http://example.com}foo', attribute 'space': The attribute
'space' is not allowed.
