RE: [xsl] disappearing line breaks within an element

["Michael Kay" <mike@xxxxxxxxxxxx>]

Interesting.

If I take this document

<e>a&#xd;b&#xd;c&#xd;d</e>

and do an identity copy with method="xml", I get

<e>a&#xD;b&#xD;c&#xD;d</e>

but if I use method="html", I get

<e>abcd</e>

The code seems to be doing this quite consciously but I can't at the moment
see why. There doesn't seem to be anything to justify it in the
serialization spec. On the other hand, outputting &#xD; to an HTML document
isn't going to do much good in terms of what you see in the browser.

The &#xd; is there in the input tree, and operations that manipulate it seem
to work fine, for example 

  <xsl:output method="html" use-character-maps="crlf"/>
  <xsl:character-map name="crlf">
    <xsl:output-character character="&#xd;" string="#"/>
  </xsl:character-map>

  <xsl:template match="/">
    <xsl:copy-of select="."/>
  </xsl:template>

gives me the output

<e>a#b#c#d</e>
