--------------------------------------------------------------

Looking further into this I think for now we can't support expressions for all attributes/properties. For example in WildFly for the {{target}} property on the {{org.jboss.logmanager.handlers.ConsoleHandler}} we use {{System.out}} for stdout while the property in the log manager itself would require {{SYSTEM_OUT}}. It's easy enough to map the resolved value, but not an expression.
{code:title=Attribute Example}
${console.target:System.out}
{code}
{code:title=Property Example}
${console.target:SYSTEM_OUT}
{code}

For the file based handlers allowing the {{relative-to}} attribute and {{path}} attribute to be written as expressions to the logging properties is likely enough. It would also be possible to support the {{level}} attribute on handlers and loggers as well. Those seem like the two most useful use-cases where an expression would likely be used.

> Allow properties that use expressions to write the expression out to the logging.properties configuration file. This allows properties passed in at runtime to affect the initial logging configuration.
