XML Professional Publisher (XPP) is a high-end publishing system which developed out of a proprietary typesetting system.

XPP is described in its product literature as a “standards-based, high performance, content formatting and publishing application for the automatic composition, transformation, and rendering of XML content into high-quality output in PostScript and PDF format.”

XPP is used to produce a wide variety of publications including Technical Documentation, Scientific, Technical and Medical Journals (STM, Directory, Dictionary and Legal loose-leaf publishing.

The XPP software came out of the Xyvision proprietary system. Xyvision was one of the first systems to combine high speed batch composition with an interactive mode displaying WYSIWYG pages, allowing for last minute corrections. At the start Xyvision was forced to build its own display hardware as the off the shelf hardware at that time was not up to the task of rapidly displaying pages. Over the years as off the shelf hardware became more powerful, Xyvision moved away from its own hardware to become a software-only vendor.

Xyvision was a publicly held company and evolved in 1995 into the privately owned company called XyEnterprise. Xyvision employed over 400 people in its top years. XyEnterprise currently employs some 80 people.

The distinctive factor in the XPP software is that each page is stored as a separate file. This allows XPP to open up a document at every page and reformat this page as a separate unit. XPP can even compose a single line as a separate unit. The ability to handle pages as individual objects makes it shine in loose-leaf publications.
