Slots are a type of element that is part of the Web Components technology suite. These elements are used to separate DOM trees. They can have one or more attributes, keywords, and choosers.

A slot is a narrow opening, usually in a machine or container. The opening is used to receive coins or dial a telephone number, and it serves a variety of purposes in many different industries. In airplanes, slots help manage air traffic, and in electronics, they allow components to pass values from one another.

The term “slot” is derived from the German word Schloss, which means “hole.” It can be used to refer to an interior opening on a copy desk or a place for entering information into a computer. It can also be used to refer to a particular time or place, such as an airport.

To slot someone or something is to find an opportunity to do or see something between various other arrangements that have already been made.

Slot allocation in air traffic is regulated by the International Air Transport Association (IATA). Its regulations favour incumbent airlines over new entrants, which causes airports to become less efficient. The rules are not without fault, however, and there is some pressure for reforms.

When describing a slot, you should identify its type and use that name to create a name attribute in the list of types. The name should be short and simple, and it should not be case-sensitive. You should also include the enumeration_value property when defining the type.
