RE: Help needed in XSD

In general, processing a schema document correctly is tough, unless you know
that it only uses a small subset of the schema language. For example, it's
not easy to apply all the rules for element wildcards, substitution groups,
derivation by extension, use of named model groups, and so on.

But if we assume that you can extract from the schema a list of element
names indicating the order in which children should appear, then it's
reasonably easy to do the transformation. For example if the list is like
this (in order.xml):

<elementOrder>
  <Type/>
  <Description/>
  <MetalHours/>
  <PaintHours/>
</elementOrder>

then you could do

<xsl:template match="Exception">
  <xsl:for-each select="*">
    <xsl:sort select="count(document('order.xml')/elementOrder/*[name() =
name(current())]/preceding-sibling::*)" type="number"/>
    <xsl:copy-of select="."/>
  </xsl:for-each>
</xsl:template>
