text.

What on earth is that? "text" in English might mean "a book" or several
other meanings. I actually can't think of a programming language that
has a "text" type. Xpath has a string type (for which you want string()
or more usually the implicit implied string value) and text nodes (which
you want text() )

I note you have consistently failed to say what you think the actual
definition should have been, or how that definition would have been more
intuitive.

$cn/text() returns the sequence of text nodes (" 1 ", " 2 ") (that is
the real and imaginary parts of the number.

Your one word non-answer gives no indication of what value you think
would have been a more intuitive definition of text() or what $cn/text()
should return, (given that element() returns element nodes attribute()
returns attribute nodes and comment() returns comment nodes.
