<blockquote type="cite" cite="mid:25522899.e4oYuXiPSZ@even-i700">For
example, if you would do a transformation from a CompoundCRS to
another CompoundCRS (or a Geographic3D CRS) with both horizontal
and vertical transformations, there is nothing in ISO:19111 to
model the composite of both.</blockquote>
<p>Actually this is modeled with <tt>PassThroughOperation</tt> + <tt>ConcatenatedOperation</tt>.
So a transformation between two <tt>CompoundCRS</tt> with a
vertical component would be like below:</p>
<blockquote>
<pre>ConcatenatedOperation (a 3D operation in this example)
PassThroughOperation (a 3D operation in this example)
coordOperation = the operation on the horizontal component
modifiedCoordinate = {0, 1}
PassThroughOperation (a 3D operation in this example)
coordOperation = the operation on the vertical component
modifiedCoordinate = 2
</pre>
