Ken, your answer is correct for the expression

<xsl:value-of select="/a/text()"/>

But it's not correct for /a/text() itself, as used for example in

<xsl:copy-of select="/a/text()"/>

Specifically, the difference between 1.0 and 2.0 behaviour is a change in
the <xsl:value-of> instruction, not a change in the meaning of the path
expression /a/text().
