<p dir="auto">I think the problem is, the iteration is not precisely described. E.g. [fs.rec.dir.itr.members] says "iteration over the parent directory resumes", "recursively iterated into", "cease iteration of the directory currently being iterated over, and continue iteration over the parent directory". These need to be defined more precisely for <code class="notranslate">depth()</code> to get an accurate definition.</p>
<p dir="auto">(Lifting the note to normative text doesn't work in my opinion, because it just adds more undefined terms, e.g. what does "immediate subdirectories" mean in the presence of symlinks?)</p>

<blockquote>
<p dir="auto">If the native format requires regular file paths and directory paths to be formatted differently, the implementation shall determine which format to use according to whether or not the last element of the generic format string is a separator. [Example: On OpenVMS, a path constructed from <code class="notranslate">"/cats/jane"</code> would considered a regular file path, and have a native format of <code class="notranslate">"[CATS]JANE"</code>, while a path constructed from <code class="notranslate">"/cats/jane/"</code> would be considered a directory path, and have a native format of <code class="notranslate">"[CATS.JANE]"</code>. --end example] [Note: POSIX and Windows use the same native format for both regular file and directory pathnames, so this paragraph does not apply to them. --end note]</p>

      <p dir="auto">What is a "directory separator character" if not a <em>directory-separator</em> ? I think if you want to make this change (here and elsewhere) we need a definition of "directory separator character", don't we?</p>
<p dir="auto">That's what the original comment suggested:</p>
<blockquote>
<p dir="auto">Should a new term "directory separator" be defined for this?</p>
</blockquote>
<p dir="auto">Without actually defining it, this makes the spec worse, by replacing the inappropriate use of a grammar term in the wrong context with a completely undefined term.</p>
