There's an updated version, v 0.2, of the FXPath document at:
In short:
FXPath - Functional XPath - is a language based on XPath. The purpose of
FXPath is to provide a language for writing extension functions in XSLT
stylesheets. The approach is to identify and define a small set of
extensions to XPath that:
  * covers a substantial part of the anticipated current need for user
    defined extension functions
  * can easily be implemented on top of current XPath 1.0 implementations.
FXPath doesn't try to solve new advanced problems, like type handling, schema
handling and database queries. Instead, it tries to make everyday stylesheet
creation and maintenance a lot easier. This doesn't mean you cannot do
advanced things, just that the focus was on solving common problems in a
convenient way.
Changes from v 0.1 include:
    * Added Function Call Steps
    * Added tokenization rules
    * Clarified fx:function content
    * Fixed some typos (certainly added some new ones :-)
