Error importing content model with 'associations' between types

[IBelyaeva]

I use Alfresco Community - 7.1.0 (rb9f449df-blocal).

When I try to import content model with 'associations' between types through Model Manager (Admin Tools -> Model Manager -> Import Model) I get the error:

"There was a problem importing the file. Try removing the existing model before importing another. The custom model doesn't support the 'associations' element."

I have created very simple model to test. If tag 'associations' is commented then all is ok. I wonder what's wrong?
