Imagine that library.xpl contains:

  <p:library ...>
    <p:declare-step name="xinclude-and-xslt">...</p:declare-step>

Consider the following imaginary command line syntax:

$ calabash -isource=- -oresult=- -s xinclude-and-xslt library.xpl

This tells the processor to load "library.xpl" and run the step named
"xinclude-and-xslt". All straightforward.

Now suppose I want to just run the "add-attribute" step. I could wrap
it in a pipeline, put it in a library, give it a name, and run it. But
since the library for the XProc builtin steps is always loaded (at
least conceptually), why do I have to do that? Why can't I just say:

$ calabash -isource=- -oresult=- -s add-attribute \
          match=div attribute-name=foo attribute-value=bar

I can't because the standard p:add-attribute step doesn't have a name.

I was wondering if we couldn't do something about that. But I don't
think we can.

However, I think I'll work around the problem by saying that if you
don't load a pipeline or a library and if you specify a step name then
the xml:id values of the standard steps are considered for the purpose
of matching the specified name.
