List of all available variables for template string

By the document, I know some variables we can use in template string such as

- Container.Name
- Data
- ...

Is there a full list of all available variables?

Start with the existing template-string documentation and trace where the documented variables, including Container.Name and Data, are defined. Identify every supported variable, then document the complete list in the relevant template-string documentation and verify that the examples match the available variables.
