为什么自动关闭脚本标记不起作用？

Question

What is the reason browsers do not correctly recognize:

<script src="foobar.js" /> <!-- self-closing script tag -->

Only this is recognized:

<script src="foobar.js"></script>

Does this break the concept of XHTML support?

Note: This statement is correct at least for all IE (6-8 beta 2).

XHTML 1 specification says:

С.3. Element Minimization and Empty Element Content

Given an empty instance of an element whose content model is not EMPTY (for example, an empty title or paragraph) do not use the minimized form (e.g. use <p> </p> and not <p />).

XHTML DTD specifies script tags as:

<!-- script statements, which may include CDATA sections -->
<!ELEMENT script (#PCDATA)>
