Updated to 0.7.4.

Changes:

Enhancements
Beginnings of RELAX NG support
      * An importer that reads DTD files and generate RELAX NG schema.
        (me)
      * A Conglomerate display specification for editing RELAX NG schema
        files. (me)

Beginnings of XHTML support:
      * A Conglomerate display specification for editing XHTML (strict)
        web pages. (me)
      * A simple template for creating new web pages. (me)

Attribute editing:
      * The Property dialog now has a tab page listing any attributes
        found in the DTD for the selected node (me)
      * Utility functions to make it easy to create attribute editors by
        binding GTK and Glade widgets to XML attributes (me)
      * A custom property dialog for DocBook <orderedlist> tags as an
        example of the above. (me)

Improvements to document type infrastructure:
      * Support for template files that can be used in the File->New
        assistant (Jeff Martin)
      * A template for creating new Conglomerate display specification
        files (Jeff Martin)
      * XML doc types can specify a file extension. For example, RELAX
        NG schema files have a ".rng" extension, and HTML files have
        ".html" extension. (me)
      * The display spec file can specify a formal Public ID for the
        DTD, and the code will try to use this, even if the XML file
        doesn't explicitly specify the DTD. (me)
      * The File->Properties dialog allows you to remove DTD
        associations, and can guess at a DTD if one is not present. It
        has a button to add the association to the document header. (me)
      * The display specification file format now supports XML
        namespaces (me)

Improvements to the "Cleanup the XML Source" tool
      * The tool now understands the difference between structural and
        span tags and doesn't force line breaks for span tags. (me)
      * Fixed some bugs and improved look of the resulting source, IMHO.
        (me)

Other Enhancements
      * Stability enhancements (me)
      * Improvements to the DTD for our display specification files (me,
        Jeff Martin)
      * Various test files should now be in the examples subdirectory of
        the tarball (Geert Stappers)
      * You can now merge adjacent paragraphs (as requested by Linux
        Weekly News) - move the cursor to the end of a <para> tag and
        press Delete, or to the start of a tag and press Backspace. (me)
      * Probably some other things I missed :-)

Fixes
      * Fixed lots of cleanup bugs when documents were closed; this
        makes the app much more stable. (me)
      * Fix for bux #118769 - a new dialog to select importers if more
        than one is applicable (me)
      * Empty context submenus are now insensitive (me)
      * Removed an unnecessary dependency on GDK 2.2 which broke the
        build on Red Hat 8
