The Tomcat web administration tool persists the changes to the config files.
Upon save, it presumably dumps a XML DOM to the xml file, and these are the side effects:

 * All comments disappear
 * Formatting is different
 * Some attributes disappear - <Server port="8005" shutdown="SHUTDOWN"> becomes just <Server>
      <Host name="localhost" appBase="webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
     Becomes <Host>
 * Some attributes are added.

<Context docBase="${catalina.home}/server/webapps/host-manager" privileged="true" antiResourceLocking="false" antiJARLocking="false"></Context>
 becomes 
<Context
    docBase="C:/Program Files/Red Hat/Enterprise Web Server/share/tomcat5/server/webapps/host-manager"
    privileged="true">
  <Listener className="org.apache.catalina.startup.TldConfig"/>
  <Listener className="org.apache.catalina.startup.TldConfig"/>
  <Listener className="org.apache.catalina.startup.TldConfig"/>
</Context>
etc. etc.

The process breaks admin.xml:

    <Context docBase="${catalina.home}/server/webapps/admin" privileged="true" antiResourceLocking="false" antiJARLocking="false">
      <Resources className="org.apache.naming.resources.FileDirContext"  allowLinking="true"/>
    </Context>

becomes:

    <Context docBase="C:/Program Files/Red Hat/Enterprise Web Server/share/tomcat5/server/webapps/admin" privileged="true">
      <Listener className="org.apache.catalina.startup.TldConfig"/>
      <Listener className="org.apache.catalina.startup.TldConfig"/>
      <Listener className="org.apache.catalina.startup.TldConfig"/>
    </Context>
