I was just pointing out that it would be hard to process XML if I
couldn't easily type the name characters - if an element name
contained a symbol how would I go about entering that symbol?

Equally, presented with some XML with characters in names that aren't
immediately obvious could be a real pain, for example <foo-bar> is
that an endash, an emdash or a hyphen?

The same encoding-style detective work could be called for: <foo?bar>
is that really a question mark?  Or does my font not contain the
glyph?  Or perhaps the encoding used didn't have a mapping...

Currently if an XPath looks right but is selecting nothing you check
the default namespace, I'm wondering if I'll also have to check the
underlying bytes to work out the actual characters too.

Perhaps XML names could be considered the programming langauge of XML
- just as everyone programs in the same Java or HTML, everyone could
be perfectly happy to program in the same XML...
