>From what I have seen and learned so far I'm not really in favor of registering Tags by parsing XML documents. While this would probably be a one time hit, parsing still takes time and we should only add to the already long startup time where this is absolutely necessary. Besides a potential performance issue, I don't see what we gain. In a recent project, we registered about 10 custom Swixml tags, some new and some were just overwriting/replacing the default tags. All this happens dynamically at runtime. The implementation of a XYZ tag may change with every instantiation of a SwingEngine class - every time a dialog i.e. is rendered. I understand that this request is mostly driven by the need to support SWT along side JFC - to be clear, I support those efforts and Swixml 2.0 design will be enabling and/ or supporting SWT - however, I don't want to replace Java with XML and this stuff definitively goes into this direction. <tag name="Applet" factory="javax.swing.JApplet" /> To me, this looks like then indrodution of a script language into Swixml, which is not very likely to succeed. Swixml was always thought to be plain, simple, small, and fast. This is not Mozilla XUL nor Luxor.
