Font index file's content

Question

In FontFactory's reference, "dvb.fontindex" has been brought in. For implementing of FontFactory, I just make a test program to parse the file "dvb.fontindex". The file's content is like this:
<?xml version="1.0"?>
<!DOCTYPE fontdirectory PUBLIC "-//DVB//DTD Font Directory 1.0//EN"
"http://www.dvb.org/mhp/dtd/fontdirectory-1-0.dtd">
<fontdirectory>
  <font>
    <name>ExampleFontName</name>
    <fontformat>OTF</fontformat>
    <filename>00000.otf</filename>
    <style>BOLD</style>
  </font>
</fontdirectory>But I got the following exception.
*** Nested Exception:
java.io.FileNotFoundException: http://www.dvb.org/mhp/dtd/fontdirectory-1-0.dtd
     at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
     at java.net.URL.openStream(Unknown Source)

     at net.n3.nanoxml.StdXMLParser.scanData(Unknown Source)
     at net.n3.nanoxml.StdXMLParser.parse(Unknown Source)From the message, it seems that error occured by "http://www.dvb.org/mhp/dtd/fontdirectory-1-0.dtd" 's unexistence.
Is the dtd file really deleted from MHP specification?
Appreciate for your help.

Thanks for replying.
The problem has been resolved.
The problem occured during implementation of FonFactory.
When testint for font index file's parsing, the problem occured.
I override the StdXmlReader, add the publicID to it, then the problem had been resolved.
