Which file type is NOT typically used for Liferay theme configurations?

In Liferay theme development, various file types serve specific purposes. CSS files are used for styling the theme, VM files (Velocity templates) are often employed for server-side templating, and FTL files (FreeMarker templates) can be used for rendering dynamic content.

The file type that is not typically used for Liferay theme configurations is XML. While XML can be utilized in Liferay for configurations such as defining portlet properties or application settings, it does not play a direct role in the theme configuration process. Theme configurations in Liferay primarily revolve around the use of CSS for styling and either VM or FTL files for rendering layouts and views.

Thus, recognizing that XML is not a standard file used specifically for Liferay theme configurations helps clarify this distinction within Liferay's theme development ecosystem.
