13.6. Wildcard Bindings
Virtual models support "wildcard" <jb:value> bindings. That is, you can bind all the child elements of an element into a Map using a single configuration, where the child element names act as the Map entry key and the child element text value acts as the Map entry value. To do this, you simply omit the property attribute from the the <jb:value> configuration and use a wildcard in the data attribute.
