Oh, maybe if someone quoted you ... :->

may I point out that while it is true for xsl:value-of, it is not always
true - exceptions (ranging from the obvious to the less obvious) include
xsl:apply-templates, xsl:variable and document()

Good point. I should have been clearer. I meant "value" in the sense of "string-value", as used in the XPath spec. (http://www.w3.org/TR/xpath#dt-string-value, http://www.w3.org/TR/xpath#function-string etc.)

Those other things return node-sets (the document() function), assign values (of any datatype) to variables, copy to the result tree, create fragments etc. and in many cases there are "values" floating around.

I guess it's so handy always to be able to know what the string-value is, that I just think of "values" meaning ways of getting access to the data in the source tree ... comes out as strings. Misleading, I guess.

(On the other hand, you could say the value of something is what you get when you ask for ...say... value-of...)

I'll try to say "string-value" from now on.

Cheers,
Wendell
