Ref. DFDL v1.0 (Jan 31, 11'), section 7.1.3.2 (Property Binding Syntax: Element Form):

I interpret from the reading that dfdl:property is child of dfdl:format, and implicitly that this form is necessary for element form
binding of dfdl attributes (properties).

Can I then infer that dfdl:format is the only dfld element that can use element form to specify properties (attributes) for itself?

Thanks in advance.
