Not really.
<command name="xpathSearch"
parameter="//ns:signal/ns:state[last()]"/>
is not easy to understand given what you want to do.

Personally, I never write recursive macro-commands. When a macro seems
to be too advanced, I prefer to write it in Java.
Note that I didn't know that it was possible to write recursive macros
before a user informed me about this feature a few years ago.
Now, this being said, it's difficult to help you without rewriting this
macro myself, which is not possible in the context of this mailing list.
I would say that:
[1] You need to separate your macro in 2 parts.
First one lets the user pick a state and selects the first signal
element of the document.
Second one [a] adds a state child element after the last state child
element (if any) of selected signal element, [b] selects next signal
element and then [c] recurses.
Note that you can pass $attvalue as a %0 parameter to the second macro.
[2] In the second, recursive, macro, I would use something like (not
sure, because I don't know the structure of your document)
<set variable="selectedElement"
context="$selected"
expression="following::pmc:signal"/>
to select next signal element.

Instead, it's also possible to use command selectNode (more efficient;
does not support namespace prefixes: use Clark's notation for qualified
names).
