LinkedIn social plugin - <script> with both src and content

Question

I'm using the LinkedIn Share Plugin Generator, which suggests using the following code:

<script src="//platform.linkedin.com/in.js" type="text/javascript">
  lang: en_US
</script>
<script type="IN/Share" data-counter="top"></script>

What could the lang: en_US be doing in that first <script> element? Surely it is invalid for there to be both a src attribute and content?

Answer 1

It isn't invalid, it just never gets passed to the JavaScript parser.

It is there to be accessed via DOM by the script.
