SMIL is an XML based HTML like language.

HTML SMIL (Amendment to HTML time) was mentioned in an early SMIL 2.0 working draft.
After SMIL 2.0 became the W3C recommendation, HTML SMIL was deleted from SMIL 2.0 and became a separate working draft called xhtm smil.
XHTML SMIL provides support for SMIL 2.0 functionality in XHTML, such as action, media, timing, synchronization, and direct conversion.
XHTML SMIL is currently a record submitted to W3C. Its intention is that XHTML SMIL can be used as the basis for integrating SMIL into XHTML.
