certainly you can keep the original document for records purposes. I mean
that the result of substituting "WHATEVER" with "whatever" ought not be
required to keep irrelevent stuff -- and if you need to keep track of
details such as whether an attribute value is single or double quoted or the
order of attributes, then you -need- an XML editor, not SAX. But this
requires you to admit you are on the 20 side of 80/20 (or 1 side of 99/1)

Perhaps to -write- XML Elements of Style, but best practices stand on their
own. Just tell Simple Bob:
These are the 10 wrenches you need to construct -any- XML application. Leave
these 2 on the shelf and don't make anything that requires either of these
tools. You can use the other 8 to your heart's desire.
and, if you:
1) Buy a toy in the store that requires one of those 2 wrenches to
a) return it and ask for a toy you can build with any of your 8 wrenches
b) take the toy to Complex Sue and have her build it for you
