Consolidate ws-rm configuration schema for spring and blueprint
---------------------------------------------------------------
Key: CXF-3975
URL: https://issues.apache.org/jira/browse/CXF-3975
Project: CXF
Issue Type: Improvement
Components: WS-* Components
Affects Versions: 2.4.4, 2.5
Reporter: Aki Yoshida
Assignee: Aki Yoshida
Priority: Minor
Fix For: 2.4.5, 2.5.1
Two almost identical configuration schemas (for spring and blueprint) are
currently used in the WS-RM component, as there are some XML attributes that
are specific to one or the other variant. The use of two schemas is associated
with an increased cost in maintaining those schemas as well as for WS-RM in
particular, a significant overhead in providing a straightforward configuration
while reusing the jaxb based configuration classes for both variants.
As defining the configuration schema for CXF's WS-RM component is on our hand
and we can define a single schema having the union of those attributes so that
it can be used by both types of configuration.
The advantage of this unification is simplicity in the implementation code as
well as in the configuration. There is one schema and one namespace to maintain
for both spring and blueprint configurations.
The drawback is a weakened syntax validation that could be avoided when two
tailored schemas are used for validation. However, there is typically always
some gap between semantically valid and only syntactically valid. And such
divergence can be documented in the schema and in the documentation to fill
this gap.
