This is a lovely example of how quoting out of context can replace giving a
counter-argument. Here's the _substantive_ part of Liam's note:

The point is (and I also made this at length before) there are few ways to
meaningfully process markup without knowing the DTD or having a stylesheet,
there are even fewer ways to process such markup (w/out stylsheet or
knowledge of the DTD) such that ignoring whitespace is something that you
_need_ to do. XML already provides you with _all_ the whitespace (unlike
original flavor SGML) -- so there's no problem with the parser hiding
significant whitespace. The only question is whether we should be addding
features to note that some whitespace is _insignficant_. In fact I believe
that small set of ways to process markup (that you don't know the meaning
of, without a processing spec), and where you _have to_ collapse or
otherwise mangle the whitespace is the _null set_.

As I asked before, I'd like to see even one example of of an application
that needs this.
