What are taggers/tags?

In Visual Studio, text decorators are one of the key differentiators that enhance this experience. These decorators, such as text colorization and CodeLens, offer contextual information to help developers understand and navigate their code more effectively. At the heart of these decorative features is the concept of taggers. Taggers are the mechanism to mark the text in the editor with hidden information, enabling the editor to adopt various text decorations later.
