Detailed Description

Selector which matches the element type, e.g.

div or circle. The selector may also include a namespace, or be a universal selector.

In the CSS source, this is represented by either a standalone type, or namespace and type separated by a pipe (|). Either the namespace or the type may be a wildcard (*).

• type
• *
• ns|type
• ns|*
• *|type

TypeSelector represents the parsed representation, if no namespace is provided it will be an empty string.
