Marks a topic as an abstract template. Template topics cannot be used directly — they must be extended by another topic using the extends property. This enables reusable topic patterns and inheritance. Template topics have relaxed model validation, meaning missing tables or columns will not cause errors. This allows you to define abstract structures that are completed by the extending topic. Refer to this community article for more information. When a non-template topic extends a template topic, it inherits all of the template’s attributes and can override or add to them.
