Some JavaScript libraries pass config parameters to the script at load time.
For example:
in dojo (async mode):
<script src="dojo.js" data-dojo-config="async:1" type="text/javascript"></script>
with firebug lite (#startOpened opens the debugger at start):
<script type="text/javascript" src='firebug-lite.js#startOpened'></script>
How does this work? How does the script collect the config parameters? Are there any limitations to this technique?
