[Springframework-developer] feature request

[Crater, J. \(EDS\) <Jon...@me...>]

i currently have a need to customize the implementation classes created
when spring parses the definitions for properties containing <map>,
<list>, etc. elements.  currently i have to subclass
AbstractXmlApplicationContext and override
initBeanDefinitionReader(XmlBeanDefinitionReader r) to call
setParserClass(Class c) with my own subclass of BeanDefinitionParser,
which in turn overrides parseMapElement, etc.  i was hoping that future
releases of spring could support this situation via out of the box
configuration.  it seems like it would be fairly straightforward to
respect a "type" attribute of the <map> and <list> (and any other)
elements to support customization of the Map/Collection implementation
without requiring custom extensions.

if there's sufficient interest, i'd be happy to contribute.
