XF 2.3 Is the <xf:head option actually used for anything?

[Stuart Wright]

I want to use a conditional to put - or not put - some custom JS and style script in the head of a template.
I see that every example of the <xf:head tag has an option.
e.g.

<xf:head option="metaNoindex"><meta name="robots" content="noindex" /></xf:head>

Is the option actually used for anything?
Thanks

This puts code into the head part of the document without altering the page_container template. I believe the option is to give it a unique ID. if you add it twice it only shows up once in source i believe. untested.
