I’m guessing someone blogged it last week (I gave up on catching up on blogs since I was almost three weeks behind), but there’s now a free home edition of xmlspy. Many of the cool features, including the schema editor, are available. However, the web services support, primarily the WSDL editor, remain only a part of the enterprise edition.
I keep wondering if someone in the community will build a WSDL editor with VSIP, esp. one that supports WSDL 1.1 and 2.0. I know CapeClear has their WSDL editor, but I find the explorer style view much less usable than the xmlspy-style graphical view.
