Do search engines understand multiple rel values?

Question

I need to have hyperlinks on my page that will look something like:

<a href="/someurl" rel="prettyPhoto[main] nofollow">Link</a>

So basically the rel attribute has two values.

I know it is valid HTML (e.g. https://stackoverflow.com/questions/1878657/multiple-values-for-rel-attribute), but my question is specifically about whether search engines will understand it.

I would hate it when SE's index stupid json strings on my site :)

I'm not entirely sure Google recognise author and nofollow when used together. Perhaps someone can expand on this if they know more? — user31756, Commented Oct 4, 2013 at 16:37

Yes, they can still read it. See example at this link

With rel="me nofollow", Google will continue to treat the rel="nofollow" as expected for search purposes, such as not transferring PageRank.

Looks to be the case indeed. Although they kinda say specifically with me. But I think you're right and SE's will just use all the values of the attribute.
