There exist other ways of linking to JS, apart from this (the usual)..

<script src="myscript.js" type="text/javascript"></script>

…that utilize other quote types:

<script src=&#34;myscript.js&#34; type=&#34;text/javascript&#34;></script>

Are these widely supported in modern browsers, and older browsers in use, such as IE6? Basically is it safe to use this method, just as you would use the regular double-quote method?

Edit: The HTML4 spec seems to allow it, but is it well supported in practical reality?

3.2.2 Attributes

  Authors may also use numeric character references to represent
  double quotes (&#34;) and single quotes (&#39;).

  For double quotes authors can also use the
  character entity reference &quot;.

    Using &#34; instead of ” is simply wrong, it doesn’t have the same meaning within the SGML and XML specifications. Argument values of elements should use either single (‘) or double quotes (“). In the old SGML specification this element

    <foo bar=&#34;quux&#34; />

    could be read as an element with the name foo, and attribute named bar with the value “quux”. However, the standard defines that unquoted attribute values should not include escaped characters. And this element

    <foo bar="quux" />

    should be read as an element with the name foo, and attribute named bar with the value quux without the quotes. This is because in SGML the quotes are optional, and everything up to the next space will be used as the value for the attribute.

    XML requires quotes.
