Add external-ref and local-ref to DTD/XSD [SPR-4052]

[spring-projects-issues]

Paul Benedict opened SPR-4052 and commented

When sharing common configuration files between projects, it is not very clear where bean placeholders come from. I do not use any IDE tooling, but I would like to derive this from reading the config. Thus I propose to extend the usage of bean references:

1. Add "external-ref" attribute to indicate that the referenced bean must come from another Spring config file, erring if it is defined within.
2. Add "local-ref" attribute to indicate the inverse. I really do like the "local" tag except there is no shorthand attribute for it, so I don't use it.

All use of xsd:ID and xsd:IDREF has been removed from the spring-beans schema for 3.1 in order to accommodate nested <beans> elements, bean definition profiles, etc.
