[XSL] - Avoiding the processing of a piece of XML

[Rocchi Cesare]

Hiyall,

I'm trying to do some transformation that doesn't succeed as I
expected.
I have some piece of xml which I don't want to be *absolutely*
changed, because
it has been carefully written. e.g. in the following code

<and>
<tag att1='val1'/>
...
</and>

I don't want "tag" to be processed because the processor (I use
XALAN-J) changes
it by substituting the single quote with the double one, and I want to
avoid this transformation. I tried to put tag in CDATA but it
transforms the "<"
in the corresponding entity &lt; and I want to avoid also this too.

How can I specify in the XSL file that a given tag has to be left
unchanged?

I tried also <xsl:copy-of> but the copy change the single quote.

As alternative, isn't possible to set the "quote for attributes" a
single quote in the transformer or serializer or, in general, the
writer?

Thanks in advance
