First of all, there is no such thing as a CDATA node. CDATA is just a
nice way to write something so that you don't have to worry about
escaping all the < and other special characters. There's only text
nodes. So what you really appear to be asking for is a way to select
specific text nodes.
And the answer is yes, of course. Just select the text nodes and
apply-templates or get their value.

No, it gets the value of the element, which is defined in the specs.
A quick summary would be all the text nodes of this element and all
the text nodes of its descendents. If you don't want to do that, get
<xsl:value-of select="text()" /> although my guess in this case you
want to get <xsl:value-of select="text()[1]" />. (or just
apply-templates on those if you do anything special with the text).

No, since it'll be turned into just escaped text via the parser. As
far as the processor is concerned, it's just a typical text node.
