Since the dynamic environment was introduced, we can safely go back to
the compiler macro approach, because the semantics of EVALUATE are
not affected anymore by the compiler's decision to use the compiler
macro or not.

"oops"

darcs-hash:124414697b6eca4a749814989db32489946b1315

Fixed xnum parsing / unparsing.
Fixed comparison operators.
Added lang() function.
Node sets returned by EVALUATE and EVALUATE-COMPILED now are automatically sorted
using document order by default.
Fixed following:: axis (again).
Fixed NODE-TEST-NAME for namespace nodes.
Numbers in XPath expressions are now never parsed into SINGLE-FLOAT.
Added SORT-NODE-SET function.

darcs-hash:cbeecb1a3180fb0663c8e9f9cae929339ddc16a4

Added atdoc documentation templates (mostly copied from Xuriella).
Renamed xpath-protocol:string-value to xpath-protocol:node-text.
Added xpath-protocol:node-text method for namespace nodes.
Added list->node-set function (a simpler version of xpath-sys:make-node-set).

- Reimplemented all xpath-protocol functions using a trampoline, e.g. so that
    (parent-pipe node)
  calls
    (parent-pipe-using-navigator *navigator* node)

- All existing methods specialize on a default value for *navigator*.
  Added a convenience macro DEFINE-DEFAULT-METHOD for that purpose.

- Only users of exotic data models need to bind *navigator* to an object
  of their choice.

  In particular, cxml/xml/xmls-compat.lisp provides a function
  cxml-xmls:make-xpath-navigator, which is implemented by
  plexippus-xpath/xmls-compat.lisp

darcs-hash:d3828b9c30d4ea787fb181678a3db979fbd16f09

Switched to dynamic bindings.
Fixed "names" of character-data nodes.

Always require the second argument to COMPILE-XPATH.  We cannot see lexical
bindings in this function.

Replaced the function EVALUATE with EVALUATE-THUNK, which always takes a
closure as an argument, never a string or sexp.  (EVALUATE-THUNK is just
a working title for this function, perhaps a better name can be found.)

New macro EVALUATE, replacing the compiler macro.

Removed *LEXICAL-NAMESPACES* and *LEXICAL-VARIABLES*.
  - don't bind *LEXICAL-NAMESPACES* in WITH-NAMESPACES
  - don't bind *LEXICAL-VARIABLES* in WITH-VARIABLES

Export EVALUATE-THUNK from the package in addition to EVALUATE.

Added a test checking that the empty namespace can be used without
having to use WITH-NAMESPACES.

Removed the call to STRING in TEST-FILTERING.  (fixme?)

darcs-hash:55b42a4c50757f63616b05dccca0cac08aa84fb4

Helper function of the same name to signal this error.

Exported XPATH-ERROR.

Added another workaround for the non-error condition that parse-number
signals.

darcs-hash:ed5d82a8ecee6fa2ff9f226148004c797a858445

Fixed:
  map-node-set
  do-node-set

Added node set iterators:
  make-node-set-iterator
  node-set-iterator-end-p
  node-set-iterator-next
  node-set-iterator-current

Exported:
  node-set-p

Added test for empty node sets:
  node-set-empty-p

darcs-hash:9e84b4035564a382ee3af2e16316bd1bb8854ab8

  Reverted CONTEXT-VARIABLE-VALUE.

  Renamed ENVIRONMENT-VALIDATE-VARIABLE to ENVIRONMENT-FIND-VARIABLE,
  which now returns a closure rather than just a boolean.

  New exported macro WITH-VARIABLES for the LEXICAL-ENVIRONMENT.
  (And tests for that.)

darcs-hash:ef5735f6293dbd141fc6644bb528e5ad44ce825e

Moved XPath parser to parser.lisp.

Moved some of toplevel API to api.lisp.

Added MAP-NODE-SET and DO-NODE-SET.

Added proper unary minus handling.

Added test cases for string representation of XPath in TEST-XPATH
(previously TEST-XPATH/UNABBREVIATED).

Made it possible to pass strings to compile-xpath.
STRING-VALUE, NUMBER-VALUE, BOOLEAN-VALUE and NODE-SET-VALUE now can handle single nodes.
Added XPATH-PROTOCOL:NODE-P.

Compiler macro for EVALUATE now issues warning instead of error if EVALUATE
is used outside lexical scope of (WITH-NAMESPACES (...) ...)

Added some of missing XPath functions - substring(), true(), false(),
boolean(), number()
