Descriptor

Netlet descriptors are surrounded by the <netlet-descriptor> tag. The signatures, if present, cover the whole <descriptor-content> tag.

Here is an example descriptor:

<!DOCTYPE netlet-descriptor SYSTEM "jtrix.dtd">
<netlet-descriptor version='1.0'>
  <!-- expiry is number of seconds since 01/01/1970 GMT -->
  <descriptor-content serial='349' starts='98438010' expires='98438030'>
    <!-- service ID is optional, but absence may prevent
    Node-wide service registration -->
