content model for <fig>?

I'm trying to determine the customary DITA structure for representing an 
image with a following caption. I presume that <fig> would be the 
appropriate container, but <fig> includes an optional <title> element 
before (not after) <image>.

I suspect this was discussed and decided long ago. Am I missing an 
appropriate structure for representing an image followed by a caption? 
Was there a rationale for placing the optional <title> at the beginning 
of the content model for <fig>? Is there an expectation that the 
processor might globally swap the order of <title> and <image> if 
appropriate?
