I am looking at the Express Web Content library and came across this code in one of the presentation templates.

<Component id="378eed8042ea34c486f7be1b1fdefad2:NC9FeHByZXNzI FdlYiBDb250ZW50L0xpc3RTdHlsZXM=" name="Express Web Content/ListStyles"/>
<script type="text/javascript" language="JavaScript" src="<Component id="4ff9280042ea35ea8705bf1b1fdefad2:NC9FeHByZXNzI FdlYiBDb250ZW50L0xpc3RTY3JpcHRz" name="Express Web Content/ListScripts"/>"></script>


Any pointers to documentation on the "Component" tag would be appreciated
