LockingSystem.lockAndWait(lockId, workflow.id);
System.debug("Obtained lock for reading Configuration: "+configElement.name+" Attribute: "+attributeName);

var attributeValue = null;

try {
	configElement.reload();
	
	//Find value of attribute in this configuration element
	try {
		attributeValue = configElement.getAttributeWithKey(attributeName).value;
		System.debug("Value of attribute "+attributeName+": "+attributeValue);
	}catch (e) {
		System.warn(e);
		System.debug("Attribute "+attributeName+" does not exist. Creating this attribute. Type of attribute will be same as that of the given default value");
		if(defaultAttributeValue == null || defaultAttributeValue == undefined) {
			throw "Unable to create the attribute.  Default value is not provided";
		} else {
			configElement.setAttributeWithKey(attributeName, defaultAttributeValue);
			attributeValue = defaultAttributeValue;
		}
	}
} catch(e) {
	System.warn(e);
} finally {
	LockingSystem.unlock(lockId, workflow.id);
	System.debug("Released lock for reading Configuration: "+configElement.name+" Attribute: "+attributeName);
}

return attributeValue;

is it possible to delete/remove configurationElement by code or actionElement?
if there is, please share the code with me.
Thank you.
