¿Cuáles son las etiquetas obligatorias en XHTML?
Un documento XHTML debe tener una declaración de DOCTYPE de XHTML. Una lista completa de todos los Doctypes de XHTML se encuentra en nuestra Referencia de Etiquetas HTML. Los elementos , ,
y <body> también deben estar presentes, y el atributo xmlns en <html> debe especificar el espacio de nombres xml para el documento.</div>
