COBCH1777 メソッドとコンストラクタは JVM 属性では無視される

The ATTRIBUTE-ID syntax is used to define attributes. Such attribute definitions may include properties and methods: these are ignored when compiling for JVM, but are included in the attribute class when compiling for .NET.
       attribute-id MyAttribute.
       method-id AttributeMethod.
       end method.
       end attribute.
