A dynamic setting is a string representation of a ConfigResolver::getParameter() call.
It allows usage of the ConfigResolver from e.g. configuration files.
Supported syntax for dynamic settings: $[;[;]]$
The following will work :
$my_param$ (using default namespace, e.g. ezsettings, with current scope).
$my_param;foo$ (using "foo" as namespace, in current scope).
$my_param;foo;some_siteaccess$ (using "foo" as namespace, forcing "some_siteaccess scope").
$my_param$ is the equivalent of $configResolver->getParameter( 'my_param' );
$my_param;foo$ is the equivalent of $configResolver->getParameter( 'my_param', 'foo' );
$my_param;foo;some_siteaccess$ is the equivalent of $configResolver->getParameter( 'my_param', 'foo', 'some_siteaccess' );
