| GWC Template Language Reference / Template Element Identifiers | |
To improve the user experience, most of the time, the page that is displaying the user interface of the application in a browser is updated incrementally. In order to apply changes to the page, elements have to be identified by a specific attribute. Usually, the name of this attribute is id. However, there are markup languages that may use another one. Therefore, the name of the element identifier attribute is configurable.
