processingjs code highlightning

Hi,

I am new to the forum, so first of all: hello to everybody! phpStorm is awesome!

I am already quite familiar with the IDE's possibilities, but I cannot figure out, how to get processsingjs syntax highlighting intergrated. As you probably know, processingjs uses its own type attribute in the script tag, which is:
<script type="text/processing" scr="processing.min.js"></script>

Nevertheless it is "nothing else but" Javascript. So I wonder: is there any way to add a new type-attribute and link it to a Javascript validator?

Thanks in advance!
Regards,
Robert
