The issue is the following:
Currently we do not allow inline CSS or JavaScript content (unless you subclass WAHtmlElement). Every CSS and JavaScript you add the root ends up as a document handler in the session. This obviously doesn't work when you don't have a session. It also hurts you when you want to go for maximum points on PageSpeed Insights. I see two possible ways forward:

1. Add checks to WAContentElement and WAHtmlRoot and check whether we have a session.
2. Add an additional method to WAContentElement for setting the inline content

I'm leaning towards the second one.

@pdebruic the following should work but is arguably not the best API

    htmlRoot stylesheet add: 'body{font-size:12px;}'.
    htmlRoot javascript add: 'alert("loaded")'

[marschall]

Syntax is

root style: 'body{font-size:12px;}'

You'll get a <style>-element instead of a <link>-element. See WARootFunctionalTest.
