This is more or less in the XSLT 1.0 spec, under Copying.

The "identity transform" described there is a template that has a relatively
low priority and recursively copies all nodes from the source tree to the
result. If you supplement that template with another that, by virtue of 
matching with a more specific node test than the other, has a higher priority, 
then you can override the identity transform for certain elements:

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

<!-- replace a ref element with its children -->
<xsl:template match="ref">

Also, just FYI, your source tree has a structure like this:

 |__element 'myelement'
      |__text '\n     '
      |__element 'p'
      |    |
      |    |__text 'This is '
      |    |
      |    |__element 'ref'
      |    |    |
      |    |    |__text 'the'
      |    |
      |    |__text ' text node'
      |__text '\n'

...that is, "This is the text node" is not very accurate; the phrase is split
among 3 different text nodes, although if you use the templates above, you'll
end up with one :)
