xsl:copy-of performs a *deep* copy, including all descendant elements and
attributes.  I believe that is the source of your confusion.  Your original
template simply matched all first order children of chapter and copied them
(the title and para elements) and their children and attributes.

Your problem (element exclusion) is a FAQ and the answer involves what is
termed the identity transform:

Other links on that page will help clarify what is going on.  I'm not
entirely clear what your output needs to be, but it seemed you wanted to
build a tree rooted on chapter and containing everything but the *imagedata*
element.  To invoke the templates I provided to accomplish this, use an
apply-templates like this:

  <xsl:template match="/">
    <xsl:apply-templates select="/SIGNATURES/SIGNATURE/chapter"/>

To collect everthing but the *imagedata* from your input, invoke the
identity transform like this:

  <xsl:template match="/">
    <xsl:apply-templates select="*"/>

The second template provided in my original response simply matches
*imagedata* elements and ignores them.  Because its match is explicit, it
supercedes the invocation of the identity transform which would otherwise
match *imagedata* with the wildcard.
