>the basic state arrows for XML processing
</P
><P
>A state is needed for global processing options,
   like encoding options, document base URI, trace levels
   and error message handling
</P
><P
>The state is separated into a user defined state
   and a system state. The system state contains variables
   for error message handling, for tracing, for the document base
   for accessing XML documents with relative references, e.g. DTDs,
   and a global key value store. This assoc list has strings as keys
   and lists of XmlTrees as values. It is used to store arbitrary
   XML and text values, e.g. user defined global options.
</P
><P
>The user defined part of the store is in the default case empty, defined as ().
   It can be extended with an arbitray data type
