Does this not then mean that the use of "structure" is something to be very
very careful with?
When I pull stuff in from WordPress I often need to use it because rather
than pulling in very "granular" data, I pull in a pre-formatted chunk of
HTML code -- perhaps a link (complete A tag, etc)...

If I was being pedantic about it -- and I'd like to be in the future -- I'd
go deeper into WordPress and pull out the components and build the A tag in
the template, thus not needing to use "structure".

The only way to avoid "structure" is to be sure that no tag markup needs to
be output, and in WordPress that's hard to do because so many of the
functions that are normally used in WordPress do just that -- they output
markup, not just data.

And that points to a big problem in WordPress for developers: there is no
real MVC structure, and no proper "presentation layer"... exactly what I'm
trying to do...

Thanks all :)
