In PI AFSDK, AFElementTemplate has an attribute "ChildReferenceTypes", but this attribute is read only. Similarly, in "PI System Explorer", we can not create child element template or reference child template. Then here are 2 questions:
1) Since we can not add child in the template level, what is the attribute "AFElementTemplate.ChildReferenceTypes" used for ? Does "ChildReferenceTypes" remains empty ?
2) An element can take instances of any template as children or reference children, is it true?
