I think that
	if ( version_compare( $wgVersion, '1.16', '<' ) ) {
		wfLoadExtensionMessages( 'SemanticResultFormats' );
	}	
is not needed in latest SVN of SemanticResultFormats.php

on the beginn MW 1.16 is already checked and mentioned as not supported

if ( version_compare( $wgVersion, '1.16', '<' ) ) {
	die( '<b>Error:</b> This version of Semantic Result Formats requires MediaWiki 1.16 or above; use SRF 1.6.x for older versions.' );
}
