The Microstar integration gives the user a single environment in which to edit both the document and its DTD. The Near & Far graphical view of the DTD also serves as a structured view for orientation and documentation for the writer or designer. From within Interleaf, the user can select a DTD, which invokes Near & Far with that DTD in the active window. The user can edit the DTD, and the software updates the document to reflect the change to the underlying structure.

Near & Far has also done more than the minimum required to claim "XML-ness": It now has an XML DTD conversion wizard for SGML DTDs. Many of the changes required for conversion can be fully automated-changing the syntax for empty elements, for example. Other changes, such as replacement of AND content models, require some user input. At first glance, it seems that Microstar has done an admirable job of automating that which should be automated and rendering to the user that which rightly belongs in the province of user discretion.

BladeRunner also integrates FastTag, the visual recognition engine developed by Avalanche and then bought by Interleaf, which can import a styled document from a word processor format, such as RTF, and create a well-formed XML document. On export, the user has a choice of publishing options.

In the past, use of the Interleaf SGML product has been limited to selected manufacturing markets. Foy Sperring, vp of product marketing, said that with the new product Interleaf hopes to increase its presence in financial applications, a move that should be strengthened by an upcoming revision of the Securities and Exchange Commission's EDGAR DTD.

BladeRunner is a layered application on top of Interleaf 6 and will be available in beta form in the third quarter of 1998. Interleaf plans nt workstation and server versions, priced at approximately $2,000 and $10,000 to $15,000, respectively.
