Yes. Note that you get the 1.0 behavior in "backwards compatibility mode",
that is, if the stylesheet specifies version="1.0".

It's most likely to cause problems if the 1.0 stylesheet was failing to
handle multi-valued data, for example

<xsl:template match="book">
  <xsl:value-of select="author"/>
</xsl:template>

in 1.0 will give you the name of the first author; in 2.0 (when you change
the version number) it will give you the names of all the authors. In most
cases this change is probably a Good Thing; if you only want the first
author you now have to say so explicitly by writing select="author[1]".
