- *			       SGML parse and stream definition for libwww
- *                             SGML AND STRUCTURED STREAMS
- *
- * The SGML parser is a state machine.	It is called for every character
- * of the input stream.	 The DTD data structure contains pointers
- * to functions which are called to implement the actual effect of the
- * text read. When these functions are called, the attribute structures pointed to by the
- * DTD are valid, and the function is passed a pointer to the current tag structure, and an
- * "element stack" which represents the state of nesting within SGML elements.
- *
- * The following aspects are from Dan Connolly's suggestions:  Binary search,
- * Structured object scheme basically, SGML content enum type.

-Structured Object definition
-
-   A structured object is something which can reasonably be represented
-   in SGML.  I'll rephrase that.  A structured object is an ordered
-   tree-structured arrangement of data which is representable as text.
-   The SGML parser outputs to a Structured object.  A Structured object
-   can output its contents to another Structured Object.  It's a kind of
-   typed stream.  The architecture is largely Dan Conolly's.  Elements and
-   entities are passed to the sob by number, implying a knowledge of the
-   DTD.	 Knowledge of the SGML syntax is not here, though.
-
-   Superclass: HTStream
-
-   The creation methods will vary on the type of Structured Object.
-   Maybe the callerData is enough info to pass along.
