<div>Yes. There isn't a CDR specifying "how" to use packages. I have one in mind, but it is bound to be
<b>CONTROVERSIAL</b>. So I have not written it upon CDR form. Plus that depends on "fixing the reader errors" (another CDR).</div>
<div><br>
</div>
<div>The note regarding packages in the proposed CDR just wants to be cautionary. I think the proposed CDR is not the place where to hash out this problem.</div>

<blockquote type="cite">Well, it really depends on the CDR; some of them may define a precise API in a specific package and/or don't allow multiple implementations to coexist (e.g. the MOP). Perhaps it would be better to remove any reference to the package
system altogether and simply state that some CDRs might be provided by multiple coexisting implementations, and, in those cases, it is not specified how to select one of them.<br>

Hi Marco,<br>
<br>
<br>
Reading the CDR, I wonder: in paragraph 2.1.2 the authors refer to the packaging system as a means to allow co-existing multiple implementations of a CDR in one image. However, the CDR doesn't specify or even advise CDR writers to use packages nor in what way.
It seems to me this CDR allows one to detect that a CDR is available in the current image, but it doesn't say *where* the programmer can find it. It feels a bit partial. Is that intended?<br>

Dear all,<br>
<br>
following up the CDR discussion that took place aside the European Lisp Symposium in Madrid a week ago, I prepared this document that specifies how a CL environment can test for the "presence" of a given CDR.<br>
<br>
I wanted to pass it around before submitting it formally to the CDR editors.<br>
