RE: Roundtripability of identity transform

No, there can be lots of other differences:

* attributes re-ordered
* redundant namespace declarations removed
* different whitespace within start tags
* use of " versus ' around attribute values
* empty elements minimized (<a></a> versus <a/>)

Subject: [xsl] Roundtripability of identity transform

Can it be assumed that the output of the transform:

<xsl:template match="@*|*|node()">
      <xsl:copy>
              <xsl:apply-templates select="@*|*|node()"/>
      </xsl:copy>
</xsl:template>

will be an exact copy of the input XML apart from:

-The output will be minus the doctype
-The output will contain any defaulted elements/attributes
-All entities will be expanded
-The output might be in different encoding (although I'm talking
differences above the byte level here).

Are there any other things to be aware of?
