-==============================================================================
-Pre-release of PXP, the XML parser for O'Caml
-==============================================================================
-
-PXP is the new, completely revised and partly rewritten validating XML parser
-for O'Caml; the old name, "Markup", has been dropped. The current version of
-PXP is still a bit experimental because it is not fully tested; however, it is
-now stable enough to be used in experimental applications.
-
-PXP will retain most parts of Markup's API; the name PXP emphasizes the
-strengths of the API: it is the Polymorphic XML Parser. The document objects
-representing the parsed file have an interesting polymorphism which allows that
-the user of the parser can control which kind of objects are actually created.
-The current API supports the element type as criterion for object/class
-selection; future APIs will extend this concept such that arbitrary criterions
-are possible (e.g. you may want to have different classes for different
-namespaces).
-
-The current development goals of PXP are:
-
-- Full XML-1.0 conformance: The current pre-release is now very close to
- strict XML-1.0 conformance. The only bigger difference to the standard is
- that PXP sometimes accepts DTDs as legal while the standard forbids them
- (non-deterministic content models).
- One of the more important improvements since 0.2.10 is the possibility to
- represent XML documents internally as UTF-8 strings, not only as ISO-8859-1
- strings. Thanks to Claudio Sacerdoti Coen who contributed a special lexer
- preprocessor hiding the details of the UTF-8 encoding in the lexer
- definitions.
-
-- Correctness of validation: The well-formedness and valididity constraints
- must be implemented as correct as possible. The last stable release had
- already a regression test covering many aspects of XML. The test suite will
- be extended.
-
-- Parsing performance: It should be possible to process large amounts of data
- in a reasoable period of time. The last stable release had many stages of
- processing that wasted time.
- The current pre-release is already 30 per cent faster than 0.2.10.
-
-- Simplicity of usage: Unlike parsers basing on imperative languages and DOM,
- the usage of PXP should be simple, even for complex tasks. The current
- parser API has already many advantages over DOM; especially it is well
- integrated into the functional and object-oriented language O'Caml. You do
- not have to deal with artificial representations like "node lists" while the
- programming environment already provides good support for list structures.
- The fact that O'Caml allows a functional programming style is interesting
- for programs transforming XML trees.

-Download the PXP pre-release
-==============================================================================
-
-The current pre-release is available under
-http://www.ocaml-programming.de/packages/pxp-pre-0.99.8.tar.gz [1]. There is
-currently no documentation for this version of the software; it is recommended
-to use the Markup manual [2] and compare it with the current module interfaces.
-
-Please note that this is work in progress; it may still contain bugs and
-irregularities.
-
-The parser works only with OCaml-3. The parser needs the netstring package [3],
-at least version 0.9.1.
-
-I am very interested in your opinion to PXP; please contact me [4].
