Fixed error range for src-ct.1

[angelozerr]

With this XML file:

<?xml version="1.1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
	 	
	<xs:complexType name="fullpersoninfo">
		<xs:complexContent>
			<xs:extension base="xs:string">
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>
	
</xs:schema>

The xs:string attribute value should be highligted as an error.
