I just read the following note in the documentation:
<sfdc:object>tag set to specify which objects your component is valid for. If an object is installed from a package, add the namespace__ string to the beginning of the object name when including it in the
<sfdc:object>tag set. For example: objectNamespace__ObjectApiName__c.
How can I dynamically reference the namespace if I have stored it in some configuration class, settings or whatever?
