stripping off
When you say select="a", do you expect to select a single "a" element, or
multiple elements?

In XSLT 1.0, if there are multiple elements, xsl:value-of will give you the
value of the first.

In XSLT 2.0, if there are multiple elements, xsl:value-of will give you all
of them, with the chosen separator between the values. But if there are
multiple elements, then normalize-space() (or normalize-unicode()) will
fail, because those functions expect to operate on a single string.

If you want to replicate the XSLT 1.0 behaviour, use a[1] to select the
first a element and discard the rest. But then you don't need a separator.

So the question is, what are you trying to achieve?
