Where to go from here

XSLT A number of developers are attempting to create prettier interfaces to XSLT, some of which focus on mapping between schemas. These tools can work in a variety of architectural scenarios.
Beyond XSLT Developers are currently confronted with a half-polished set of tools. They can process nodes, but XSLT has some pretty well-documented limitations for creating markup structures where none exist. Something that combines the node-approach with more powerful text-processing capabilities might help developers
Helping humans visualize data and documents Document and information flows aren't usually that difficult to understand until we aggregate them and demand 'scalability'. By leaving control over data and documents with those who create and manage them, we can tackle these problems in smaller pieces which are easier to present to people with a solid understanding of their needs, but little understanding of transformation tools.
Getting over the fear and loathing Many of the problems, including business problems, which XML is best at solving are familiar. By leaving them with individuals and organizations, and maintaining their control over their information, we can give them a sense of ownership rather than new concerns about job security and their skills being devalued.
