There are a number of XML content creation tools packages on the market. Users should consider a number of key features when evaluating these offerings. An XML Developer Editor is a key tool for any business moving content to XML. IDE tools should not only work with DTDs and XML schemas, they should include full creation and debugging tools for them. They should allow users to design, debug, and deploy the wide range of style sheet transformations (XSLT) for repurposing of content for multi-channel publishing. The package should offer validation, giving the writers constant assistance in doing the right thing. Ideally this would be continuous real-time validation against the schemas content model rules, and it should not allow any possibility of error. The best tools will also display a context-dependent list of the allowed or available elements that users can add at the documents current insertion point. This can be in the guise of a floating palette or separate window pane, or a drop-down menu when an open tag is typed, or via a right-click at the insertion point. Other things to look for include tags-on views, grid views, source-code views, tag auto-completion, line indenting, an XSLT processor, spell checking capabilities, multilingual support for integration with translation tools, and template documents that authors can use as a starting point, with the knowledge they are valid for certain schemas and offer support for specific output style sheets.
