Comentarios

La Type propiedad solo se puede establecer en tipos y enumeraciones primitivos.

XmlTextAttribute También se puede aplicar a un campo que devuelve una XmlNode matriz de XmlNode objetos o .

Puede aplicar a XmlTextAttribute un campo o propiedad que devuelve una matriz de cadenas. También puede aplicar el atributo a una matriz de tipo Object , pero debe establecer la Type propiedad en string. En ese caso, las cadenas insertadas en la matriz se serializan como texto XML.
