Re: namespace problem

You need to match a document that has elements <doc>, <p>, <Char> that are
in *no namespace*, where the name has no namespace name, just a locsl name.
Your output document is supposed to be in the namespace "
http://www.w3.org/1999/xhtml", and you'd like to use the shortened notation
known as *default namespace*. In the 2nd version of your XSLT you introduce
a default namespace, and, sure enough, the matches written without a prefix
aren't in the no namespace ghetto any more.

You may, however, at any time cancel the definition for the default
namespace by writing

xmlns=""

and everything below that has no prefix hasn't a namespace name either.

  <xsl:template xmlns='' match='char' mode='#all'>
    <c><xsl:apply-templates /></c>
  </xsl:template>
