No, it does not.  And there is no “javascript”; certainly there is no such 
thing as “valid javascript” because ECMAScript implementations differ from 
one another.  At most, there are conforming ECMAScript implementations such 
that they agree in the core features as specified.  See my sig.

It MUST NOT contain SGML-based markup tags except in literals.  (Formerly, 
this included XML literals in *Mozilla* JavaScript, as part of its 
“ECMAScript for XML” [E4X] support.  Unfortunately, this support has been 
discontinued. [1])

“Embed” is not the proper term here.  “Contained” is.

That would be a _“head” element_.

No, that would mean to wrap it in

  <script>

  <script>

But you need to "wrap" it in

  <script …>

  </script>

Elements are _not_ tags. [2][3]
