= ResourceX --- Flex Resource Bundle Extensions = If you examine CSS style sheets, property files and their ilk are really fine--grained cousins of the "plugin" architecture used by successful platforms like Eclipse. Every place you access a style is like an extension point, the style value you supply is the extension and the property file or style sheet is the plugin. It occured to us that we could use the !ResourceManager API in the Flex SDK to supply more than simple string values and skin class references, but the limited syntax of property files wasn't the place to do it, we'd rather use our favorite declarative markup language --- MXML.
