    <remarks>
      <para>This attribute can be applied to parameters, fields, or return values.</para>
      <para> Each data type has a default marshaling behavior that is used
      if this attribute is not present. This attribute is only required when a type
      can be marshaled as more than one possible types. <block subset="none" type="note">The <see cref="T:System.Runtime.InteropServices.UnmanagedType" /> enumeration specifies possible
      data types.</block></para>
      <para>Compilers are required to not preserve this type
      in metadata as a custom attribute. Instead, compilers are required to emit it
      directly in the file format, as described in Partition II of the CLI
      Specification. Metadata consumers, such as the Reflection API, are required to
      retrieve this data from the file format and return it as if it were a custom
      attribute. </para>
