ALL SORTS OF TODO ITEMS
- c99 strip, has been renamed, and refers to MXSLT_DEBUG.
  Should update docs and regular expressions.
- add support to retrieve ENVIRONMENT variables from xslt
  stylesheet, like HTTP_HOST
- try to compile on Mac OS X (now I can :)
- check that mod-xslt works properly with mod-proxy
- allow mod-xslt to be enabled/disabled based on browsers Accept headers
- accept parameter parsing. Mail from Tiago.Tuxkiller:
  <?xsl-stylesheet type="text/xsl" noprocess="no" accept="admin" href="http://teste.com/estilo/fotolog/admin.xsl"?>
  <?xsl-stylesheet type="text/xsl" noprocess="no" accept="mini" href="http://teste.com/estilo/fotolog/mini.xsl"?>
  <?xml-stylesheet type="text/xsl" href="http://teste.com/estilo/fotolog/lista.xsl"?>

  And I can't change between:

  and
  http://200.222.222.222/html/2007/08/15/13530858.xml?admin
  or

- building on gentoo (reported by Bill Farrar <bill.w.farrar at gmail.com>)
  libtool: compile: unable to infer tagged configuration
  libtool: compile: specify a tag with `--tag'
  make[1]: *** [modxslt.lo] Error 1
  make[1]: Leaving directory
  `/home/rbrown/Downloads/Tar/modxslt-2005072700/sapi/apache2'
  make: *** [sapi] Error 2
  
  After messing around with this for a while, I turned to the libtool
  mailing list, who recommended that I edit sapi/apache2/Makefile.in to
  append --tag=CC to this line:

  [...]
  modxslt.c  -fPIC -DPIC -o .libs/modxslt.o
  modxslt.c:23:21: error: sockios.h: No such file or directory
  modxslt.c: In function 'mxslt_ap2_setanyiplist':
  modxslt.c:495: error: 'SIOCGIFCONF' undeclared (first use in this function)
  modxslt.c:495: error: (Each undeclared identifier is reported only once
  modxslt.c:495: error: for each function it appears in.)
  modxslt.c:513: error: 'SIOCGIFADDR' undeclared (first use in this function)
  modxslt.c: At top level:

  make[1]: *** [modxslt.lo] Error 1
  make[1]: Leaving directory
  `/home/rbrown/Downloads/Tar/modxslt-2005072700/sapi/apache2'
  make: *** [sapi] Error 2
  
  I got round this by adding the following to sapi/apache2/modxslt.c:

  #include "/usr/include/linux/sockios.h"

- eval screen and pippo pluto = pluto -> TRUE -> must be FALSE
- add in the README.Debian file notes on how to setup 
  modxslt both for apache and apache2
  
+ mail with latypoff@yandex.ru -- investigate why mod-xslt
  ignores xsl:output in imported stylesheet while original
  mod-xslt seemed to work correctly.
+ change variable behavior to simplify escaping ...
+ correct the problems due to the new document extensions
  (mail of Toby White...) -- set the outputFile libxslt
  variable -- provide some mechanism for users to 
  override it -- consider adding a virtual path mechanism,
  or something like that ...
- start writing mod-xslt recipes ...

- make mod-xslt variables and parameters ``more'' 
  accessible (right now, they can only be accessed
  using mod-xslt own extensions)

SAPI PARAMETERS
- add XSLTPolicy <display|page|error>, to let user decide
  what to do with documents without a valid <xml-stylesheet
- correct If-Modified handling as in mails with Patrick
  Ben Koetter

LIBRARY
- !!cleanup the library!!
- initialize and destroy scanner status
  only at init time, not every time a string
  has to be evluated
- use xmlSAXParseFile instead of other standard
  functions
- add XPath _function_ to access mod-xslt variables
- add XPath _function_ to open up another url
  (like open, but with the ability to fake being a client
  and pass over POST parameters and headers)
- add xml instruction for external elements

  MODXSLT_EXPRESSIONS
  - = and ==, problem with long numbers and strings 
  - variables accepted by lex are not the same handled
    by replace string - and are not the same handled by
    value-of!!!

SAPI
- apache 2.0 cacheing 
- apache 1.3 cacheing
- wildcards in mime types
- save xml document from dynamic documents
  only when an error verifies
- error output in html documents
- add some way to load external modules and plugins

CONFIGURE SCRIPT stuff
- add flag to detect flex and bison
- check for pcre version

DONE
* allow disabling signatures at run-time
D add XSLTLogStylesheet to let user log how a stylesheet
  was chosen -> this mechanism is beign replaced by a much
  more powerful mechanism
* correct local:// url handling under apache2 
* verify xsl:param usage as mail from Eric Anderson
* remember to add notes about AddOutputFilterByType,
  remember to tell giskard ..  (manual done, still
  need README.Debian)
* remove \n from debug_print ...
* modxslt-config, returns garbage when --list is used.
  Something is wrong somewhere.

* add XSLTForceStylesheet
* apache 1.3 locking issue
* verify apache parameters
* ap_overlay_tables is wrong
* apache conditional stylesheet
* apache 2.0 worker 
* memory leak when calling mxslt_ap2_child_init()

* uhm - very strange ... seems like that accessing
  a file in a forbidden directory causes strange
  errors (chmod 2770 /home/projects)
* build process, update to build library 
  _and_ binaries
* in local urls, use subrequests to avoid 
  denyal of service
* handle server port in local and http
  urls!!!!
* watch out! when making sub requests, switch
  url parameters to those of the new request!!!
* note temporary file name
* delay handling of local urls
* apache1: lookup ip addresses using ioctl
* use two hashing tables to keep parameters
* crash with access denyed

* avoid sapi flags being used for other stuff
* add pthread detection code in configure.ac
* add detection code for xsltCopyTextString, available
  from libxslt 1.0.32 and greater
* add detection code for interface ioctl
* add detection code for nano patch in configure.ac
