/** Part of the implementation of `TLoggingElementBuilderTemplate`
* that does not need to be template.
*
* If this was implemented in this header, the xmlElement implementation
* would leak to sources including this header.
*
* Plugins are including this header. As a result they would include
* the xmlElement implementation if it was not hidden in a cpp.
*
* FIXME: The xml concept (forward declared) is still leaked to the plugin.
* A solution would be have two level of builders:
* - a PluginBuilder that wraps the plugin
* - and an ElementBuilder that wraps the PluginBuilder
* This way the plugin can only see the PluginBuilder and is not
* contaminated by any core specific concept.
*
* @param[in] xmlElement the XML element
* @return the "Name" attribute value of an xml element or
* empty string if attribute is not present
