     Your interpretation looks right to me.  Certainly the x parameter of
I2OSP would not be what is set equal to 20, since that's the input value.
We might even want to add in the previous sentence that r goes first in the

Subject:  a typo in section 6.4.1 ?

>   Section 6.4.1 DSA refers to  a parameter k in
Integer to octet-stream conversion must be done according to the I2OSP
operation defined in the RFC 2437 <ftp://ftp.isi.edu/in-notes/rfc2437.txt>
[PKCS1] specification with a k parameter equal to 20.
however the supplied link leads to a text where the parameter used is named
l (small 'L').
Input: x nonnegative integer to be converted
 l intended length of the resulting octet string
Output: X corresponding octet string of length l; or "integer too large"

To avoid confusion among readers we may want to change the draft to reflect
that. (unless I misunderstood l for another parameters)
