Incorrect error range for cvc-identity-constraint.4.1

[angelozerr]

Given this XML file:

<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5"> 
    
		<servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

		<servlet>
			<servlet-name>dispatcher</servlet-name>
			<servlet-class>
					org.springframework.web.servlet.DispatcherServlet
			</servlet-class>
			<load-on-startup>1</load-on-startup>
	</servlet>
	
</web-app>

The error range is not correct (at end of the servlet-name) :

The error range should higlight the dispatcher text node.

In the previous sample it is the text node "dispatcher" that it must be highlighted but when I tried the issue redhat-developer/vscode-xml#716 if you open the text.xml you will see the same error but it os for attribute:

For writting test I think it should be good to write a XSD file (stored in the test resources folder) with those constraint.
