Cdodge/return attributes for course about

@mattdrayer quick addition to help Tivs out in his work to tie in an about video for a course
Ok, I ran the test and took a look at the resulting attributes container -- I can see that the two items being returned are the 'class' and 'data-videoid' value.  It seems odd that we're returning class as a standalone value and then we're returning it again as an attribute item.  While this gets the job done in terms of the client's request, is there a way to make the overall workflow here simpler?
