var fastMarker = L.marker([50.5, 30.5], { tags: ['fast'] }).addTo(map); 
var slowMarker = L.marker([50.5, 30.5], { tags: ['slow'] }).addTo(map);
var bothMarker = L.marker([50.5, 30.5], { tags: ['fast', 'slow'] }).addTo(map);

	data: ['fast', 'slow']
}).addTo( map );

Set data from external url or ajax

}).addTo( map );
