With the following DTD:

    <!-- library-list: Root element with versioning -->
    <!ELEMENT library-list  (library)*>
    <!ATTLIST library-list  version CDATA   #FIXED  "1.0">
    <!ELEMENT library       (segment)*>
    <!ATTLIST library       name    CDATA   #REQUIRED>
    <!ELEMENT segment       EMPTY>
    <!ATTLIST segment       address CDATA   #REQUIRED>

there's no way to have several segments at different offsets, because
segments aren't allowed to have names.  Shouldn't segments have a name
attribute?
