--- Comment #2 from Tim Mills <tim@cbcl.co.uk> ---
I'd suggest allowing simpleMapExpr to contain a sequence of two or more
pathExpr, mirroring the XQuery grammar:

[106]        SimpleMapExpr        ::=        PathExpr ("!" PathExpr)*

(I've gone for 2 or more, rather than one or more, but I don't think it
matters).

  <xsd:complexType name="simpleMapExpr">
    <xsd:complexContent>
      <xsd:extension base="expr">
        <xsd:sequence minOccurs="2" maxOccurs="unbounded"/>
          <xsd:element ref="pathExpr"/>
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>

Here's the corresponding change to the transformation.

  <xsl:template match="xqx:simpleMapExpr">
    <xsl:value-of select="$LPAREN"/>
    <xsl:value-of select="$SPACE"/>
    <xsl:apply-templates select="xqx:pathExpr[1]"/>
    <xsl:value-of select="$SPACE"/>
    <xsl:value-of select="$RPAREN"/>

    <xsl:for-each select="xqx:pathExpr[position() != 1]">
      <xsl:value-of select="$NEWLINE"/>
      <xsl:value-of select="$EXCLAMATIONMARK"/>
      <xsl:value-of select="$SPACE"/>
      <xsl:value-of select="$LPAREN"/>
      <xsl:value-of select="$SPACE"/>
      <xsl:apply-templates select="." />
      <xsl:value-of select="$SPACE"/>
      <xsl:value-of select="$RPAREN"/>
    </xsl:for-each>
  </xsl:template>
