Script dependency order

Hi
I'm including the script for the datepicker before ui.core. Something
like this
<script src="jquery.js"/>
...
<script src='ui.datepicker.js'/>
...
<script src="ui.core.js"/>
This seems to work fine, but I was hoping someone could clarify that
it's ok to link to the datepicker out of strict dependency order?
Thanks
Paul
