Property Place holder for namespaced attributes is not working

What steps will reproduce the problem?
As per the wiki page https://github.com/Comcast/jrugged/wiki/Spring-Namespace-Example, I can use property place holder for jrugged:perfmon attribute to turn performance monitoring On/Off by just making changes in property file. However, spring doesn't support BeanFactoryPostProcessor for namespaced attributes and tags. Thus leaving properties referred as ${propertyKey} as it is when the PerformanceMonitor bean created in Decorator.

What is the expected output? What do you see instead?
${propertyName} in xml configuration for jrugged:perfmon or jrugged:methods should be replaced with "propertyValue" configured in properties file using Post processor. Or, this deficiency should be be noted in the wiki page.

What version of the product are you using? On what operating system?
Jrugged 2.4 (core and spring)
