Agreed.

But then XQueryX was never intended as a language for humans. It does have its uses when generating XQuery code programmatically as it can be validate before transforming to XQuery using XSLT.

No.

a) the first drafts of what became xpath did use xml markup
b) there is a standardised xml markup for all of xquery (which includes 
xpath)

It's not a limitation of XML, it's a limitation of humans.

c) ? Why do we resort to non-XML syntax?

Try writing a few xpressions using XqueryX by hand and you'll soon see:-)
