When you check the XML pages using the W3C validator, you get some errors. Some of them can be easily fixed. However, two types of them are due to W3C limitations :

- maxwell.xml : the declared "vec" entity is not parsed. This seems to be a bug of the W3C validator.

- mixing.xml : the XHTML elements are not accepted inside a MathML test. The doctype used is only for XHTML as the host language.

Reproducible: Always

Fixes some errors.

This is an old bug but my patch seems still appliable.

 Mixing MathML markups and other markups to get special effects</h2>

I would put the div after the h2.

-    <html:img src="chrome://communicator/skin/brand/throbber-anim.gif" />
+    <html:img src="chrome://communicator/skin/brand/throbber-anim.gif" alt="" />

I would use alt="throbber".  Here the img is not just for formatting but
important for the demonstration, so shouldn't just become invisible.

The <br /> here imply that the author wants a line break, and that would
certainly make this easier to read.  No newline is being generated, but I'd
rather not remove the <br /> until this is rewritten with appropriate markup
that does provide the line break.

Replace <br/> by <mspace linebreak="newline"/>

It seems that the W3C does not define inclusion of XHTML inside MathML, so I think we can't make the file mixing.xml valid for the moment:

I replaced the <br/>'s inside MathML by <mspace/>'s. However, it looks like Mozilla does not support the attribute "linebreak" (anyway the <br/>'s currently do not make any likebreak). See bug 380266

I don't actually understand why entities declared in can't be used be used in other entity declarations, but these changes look good anyway, thanks.
