Universal Subtitle Format (USF) was an ambitious project created for proportionate a clean, documented, powerful and easy to use subtilte file format. It's based on XML for some the following reasons: flexibility, unicode support, hierarchic system and easy to administrate.

USF subtitles are usually used in Matroska Containers.

The format has come under a lot of criticism, especially from the fansub community, because compared to the format it aims to replace, Advanced Substation Alpha (which is based on comma-separated values), it's more verbose and far harder for software to read, write and manipulate it. It's also much harder to edit "by hand" in text editors such as notepad. Those reasons, as well as the lack of a generic cross-platform parsing/rasterizing library and mature editing programs that support it natively, have made the format unsuccessful in being widely used.

No known media player software implements more than basic support for this format. VSFilter and the VLC media player (starting with the upcoming 0.9.0 release) are able to extract the subtitle text, timing information and very restricted formatting.
