XMLmind XML Editor allows to edit large, complex, modular, XML documents. It makes it easy mastering XML vocabularies such as DocBook or DITA. (More info.)

As you can see it in the screen shot below, XMLmind XML Editor is not a tool for programmers. Its users are generally technical writers.

oXygen is a cross-platform XML Editor. Besides the top-of-the-line XML source editing support, it features a CSS driven WYSIWYG XML editing mode allowing the content authors to visually edit DITA documents. oXygen features include out-of-the-box integration with the DITA Open Toolkit and can be easily customized to match your DITA editing and publishing needs.

This utility parses all the DITA files referenced in a ditamap file (including all conrefs in any file) and gives a list of all conditional attribute values found in product, platform, audience and otherprops. Using this list, you can check that all the values are valid and that there are no mistaken values. You can then choose which attributes to include and exclude, and automatically generate a ditaval file.
