== Why is this an issue?

The ``++<object>++`` tag is used by Internet Explorer 3.0 or later on Windows platforms or any browser that supports the use of the Flash ActiveX control. The ``++<embed>++`` tag is used by Netscape Navigator 2.0 or later, or browsers that support the use of the Netscape-compatible plug-in version of Flash Player.


When an ActiveX-enabled browser loads the HTML page, it reads the values set on the ``++<object>++`` and ignores the ``++<embed>++`` tag. When browsers using the Flash plug-in load the HTML page, they read the values set on the ``++<embed>++`` tag and ignore the ``++<object>++`` tag.

There doesn't seem to be a consensus on this, and I am unsure if this rule should be enabled by default.


http://helpx.adobe.com/flash/kb/object-tag-syntax-flash-professional.html does not include the embed tag for instance.

IE 3.0, Netscape 2.0, sounds like very serious reasons to comply to this rule ;)


I didn't find anything much better, the provided rationale is a bit blur.

The rationale behind this rule is obsolete, nowdays there are different recommended ways of inserting Flash animations.
