You meant that I likely to get an equivalent form?

Basically, I need more documentation.  It is not obvious how to get all
defined elements, for example.  And more examples, if possible.  :)
What I want to know is how:

    to obtain the list of public identifiers from catalog;
    to parse a specific DTD (using its public or system id);
    to get DTD information for a given document.

Under DTD information I understand the list of elements (with theirs attributes)
and a way for figuring out how the elements may follow one another.  Having
written my previous message, I understood what the content_model is, and how
to make use of it.  I am only afraid that since it is not documented (and,
therefore, is not fixed) it may easily be changed should you find a different
way for validating XML files against DTD.
