  • Probably none, as much as some people choose .htm and others .html for their HTML documents some people choose .xsl for an XSLT stylesheet and others choose .xslt for an XSLT stylesheet.

  • As others have said, there is no practical difference (unless you're using DOS/Win 3.x that does not support 4 character extensions.  This is basically the reason why file formats often have both 3 letter and 4 letter extensions).

    Visual Studio defaults to .xslt.

    On the other hand, the XSLT Specification (http://www.w3.org/TR/xslt20/) always uses .xsl except in one line where it says:

    XSLT documents are most often identified with the extensions ".xsl" or ".xslt".

    Kind of makes it hard to decide, doesn't it :)
