XHTM file extension - Extensible HTML document

What is xhtm file? How to open xhtm files?

The xhtm file extension is associated with the Extensible HTML (XHTML) markup language.

XHTML is a family of current and future document types and modules that reproduce, subset, and extend HTML 4. XHTML family document types are XML based, and ultimately are designed to work in conjunction with XML-based user agents.

XHTML documents are XML conforming. As such, they are readily viewed, edited, and validated with standard XML tools.

XHTML documents can be written to operate as well or better than they did before in existing HTML 4-conforming user agents as well as in new, XHTML 1.0 conforming user agents.

XHTML documents can utilize applications (e.g. scripts and applets) that rely upon either the HTML Document Object Model or the XML Document Object Model.
