Can I use a template that contains attributes in a UI Page?

Can I use a template that contains attributes in a UI Page?

1.     When a template is created with some attributes on the Data TAB and later is used in a UI Page using a Referenced Template, the editor shows an error informing that: The Data Tab must not have specified any attribute or business object. Can I use a template that contains attributes in a UI Page or not? Is normal this behavior?
