==============================================
Diazo - We Write XSLT, So You Don't Have To
==============================================

Diazo allows you to apply a theme contained in a static HTML web page to a
dynamic website created using any server-side technology. With Diazo, you can
take an HTML wireframe created by a web designer and turn it into a theme for
your favourite CMS, redesign the user interface of a legacy web application
without even having access to the original source code, or build a unified
user experience across multiple disparate systems, all in a matter of hours,
not weeks.

When using Diazo, you will work with syntax and concepts familiar from working
with HTML and CSS. And by allowing you seamlessly integrate XSLT into your
rule files, Diazo makes common cases simple and complex requirements possible.

For detailed documentation, please see diazo.org_.

* Python 3 support.

1.0.6 (2014-09-11)
------------------

* Use formencode's xml_compare method to compare test results. This solves test
  failures on several systems.
  [timo]

* Also evaluate if-not-content. However, we are at risk of replicating
  apply-conditions.xsl in it's entirety. this needs refactoring.
  [lentinj]

  xml:lang attributes when the html tag's attributes are copied.

------------------

------------------

* Support selectors matching multiple elements for merge attributes, e.g.
  ``<merge attributes="class" css:theme="body" css:content="#one, #two"/>``
  [elro]

* Also evaluate merged-condition. This means a rule tag will turn red
  when a condition on an outer rules tag doesn't match.
  [lentinj]

* use boolean(), not count() for if-content. Otherwise we
  generate expressions like "count(nodeset and other_nodeset)",
  which aren't valid.
  [lentinj]

  [lentinj]

* Debugging output.
  [lentinj]

* Allow attributes (i.e. xml:id) to pass through on drop @attribute nodes
  [lentinj]

1.0.1 (2012-05-09)
------------------

* Fixed to not apply absolute prefix for relative urls starting with '#'.
  [datakurre]
