------------------------------------------------
Hi Bryan,
>It seems like it would be nice to perform the special character encoding of the
>XML attribute strings *prior* to composing them into quoted substrings in the
>XML tag string,
>since then replaceInAttribute() wouldn't have to go searching for the start
>and end of
>the attribute string to find it.
Since we're getting the attributes as quoted substrings from the database query
it self,
I'm not quite clear whether this is possible.
> Plan exporter tool produces broken output if query contains less-than operator
