Where to get acquainted with the structure of the model xml-file in Alfresco?

[varlok]

The documentation for Alfresco developers provides examples of xml files for creating models.

Example: Adding an association | Alfresco Documentation  

The example describes the association (Peer Associations). But also I know that Alfremko has  Child
Associations and the corresponding tags for it, but this is not written in the documentation or I do not look well. 

Here is the question: where can I find the fullest description of the syntax and all the tags and attributes that can be used to create the data (content) model (and the flow model) in Alfresco?

You can have a look at this old wiki document "Data Dictionary Guide" that got migrated to this platform.
