I was looking at some Seaside code today and noticed that it said

html tableCaption: 'blah'.

Rather than

html table tableCaption: 'blah'

In other words, as far as Seaside was concerned the tableCaption tag was nothing to do with the table tag.  This struck me as slightly odd. Somehow I would have expected the 'child' tags of table to be created through messages to the parent table.  However, that clearly isn't the case, and now that I have looked more closely at the Seaside tag structure, that seems to be the case for most of the tags. 

I am keen to understand what makes good Smalltalk design, so could someone explain why making the tags independent is a better way of doing it?

Thanks
