> The work in FALCON-1434 added the ability to specify properties for the purpose of enabling
scheduler selection. However, this could be more generally useful as a means for users to
submit custom properties that will be visible in Oozie workflows.
> This will enable users to reference properties in the entity XML itself and passing these
properties down to workflows. For example, a process scheduled with the command:
> {code}
> bin/falcon entity -schedule -type process -name helloFalconProcess -properties custom.property:HEY
> {code}
> can reference the property _custom.property_ in the process XML as
> {code:xml}
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <process name="helloFalconProcess" xmlns="uri:falcon:process:0.1">
>   ...
>   <properties>
>     ...
>     <property name="customProperty" value="${coord:conf('custom.property')}"/>
>     ...
>   </properties>
>   ...
> </process>
> {code}
> An Oozie workflow can then easily make use of such property:
> {code:xml}
> <workflow-app xmlns="uri:oozie:workflow:0.4" name="hello-falcon-wf">
>   ...
>     <java>
>       ...
>       <arg>--customValue=${customProperty}</arg>
>       ...
>     </java>
>     ...
> </workflow-app>
> {code}
