UndefinedObject(Object)>>doesNotUnderstand: #externalTypeAlignmentUndefinedObject

after replacing the library name #1 

I get 

`UndefinedObject(Object)>>doesNotUnderstand: #externalTypeAlignmentUndefinedObject `

I wrote with @estebanlm in discord private chat and he found out that I have to do

`XmlEnumeration allSubclassesDo: #initializeEnumeration`

after that, it works.

I will call this in my fork after loading but report this, here.
