Depending on the particular "formatting task" this can be done in
different ways -- even using <xsl:foreach>

Here is a simple example that can replace the sorting code in the
previous solution and that produces your wanted output:

    <xsl:variable name="vSorted" as="xs:string*">
     <xsl:perform-sort select="distinct-values($vTypes)">
      <xsl:sort select="."/>
     </xsl:perform-sort>
     </xsl:variable>

     <xsl:value-of select=
      "$vSorted/concat('...Some other text (', ., ') More Text....')"
separator="&#xD;&#xA;"/>


So, the complete transformation in this case is:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:xs="http://www.w3.org/2001/XMLSchema";>
  <xsl:output method="text"/>
  <xsl:template match="/*">
    <xsl:variable name="vTypes" as="xs:string*">
      <xsl:apply-templates select="*/@type"/>
    </xsl:variable>
    <xsl:variable name="vSorted" as="xs:string*">
     <xsl:perform-sort select="distinct-values($vTypes)">
      <xsl:sort select="."/>
     </xsl:perform-sort>
     </xsl:variable>

     <xsl:value-of select=
      "$vSorted/concat('...Some other text (', ., ') More Text....')"
separator="&#xD;&#xA;"/>
  </xsl:template>
  <xsl:template match="property/@type[. eq 'foo']">
    <xsl:sequence select="'a', 'b'"/>
  </xsl:template>
  <xsl:template match="property/@type[. = ('bar', 'baz', 'bof')]">
    <xsl:sequence select="'b', 'c'"/>
  </xsl:template>
  <xsl:template match="property/@type" priority="-1">
   <xsl:sequence select="'c', 'd'"/>
  </xsl:template>
 </xsl:stylesheet>


and when applied on the same XML document:

<object>
   <property name="name" type="foo"/>
   <property name="key" type="bar"/>
   <property name="size" type="baz"/>
   <property name="age" type="bof"/>
   <property name="grade" type="goo"/>
 </object>

it produces the wanted result:

...Some other text (a) More Text....
...Some other text (b) More Text....
...Some other text (c) More Text....
...Some other text (d) More Text....

Instead of the function concat(), you may call an xsl:function that
you have written yourself, that could perform more subtle formatting.
