COBCH1682 XML コメントに解決できない cref 属性 '%1$s' がある

The cref attribute specified a name that cannot be resolved to a known type or member.

In the following example, the type redClass is missing, and therefore cannot be resolved. You must either remove or edit the reference, or add the type to your code.

$set ILDOC"cbloutput.xml"
 class-id new.
 *>> <summary> 
 *>> Contains the name of <see cref="redClass" /><see cref="whiteClass" /><see cref="blue" />. 
 *>> </summary> 
 01 blue  string.
 ...
 end class.
 class-id whiteClass.
 ...
 end class.
