This is certainly the most useful behaviour for the stylesheet,
but the spec says "The xsl:message instruction sends a message in a
way that is dependent on the XSLT processor.", so I don't think the
other processors are necessarily wrong.

In any case, I'm not sure that Saxon is actually giving you the behaviour
that you want. If you make the following modification to your stylesheet


<xsl:template match="/">
  <xsl:variable name="message">
      <xsl:message>a message</xsl:message>
      <xsl:text>some text</xsl:text>
   </xsl:variable>

   <xsl:message>real message</xsl:message>  <!-- new -->
   <xsl:value-of select="$message" />
</xsl:template>

you get:

a message
real message
<?xml version="1.0" encoding="utf-8" ?>some text

It would appear that the message isn't actually being stored as you
suggest.
