<br>
<span style="font-family:"Calibri",sans-serif">The Sequence-Controlled DP procedure extends the EXECUTE-DIRECTIVE operation (4.8.4.4) with the ‘reset’ directive (4.8.4.4.2) and associated directive-qualifier (4.8.4.4.3).
</span><br>
<span style="font-family:"Calibri",sans-serif"> </span> <br>
<span style="font-family:"Calibri",sans-serif">The current phrasing of 4.8.4.4.3.1 states “The
</span><span style="font-family:"Courier New"">directive-qualifier</span><span style="font-family:"Calibri",sans-serif"> shall identify the
</span><span style="font-family:"Courier New"">next-data-id</span><span style="font-family:"Calibri",sans-serif"> parameter value …”. Although it should be obvious that this is *<b>only</b>* true when the directive-identifier is ‘reset’, it doesn’t explicitly
state that and could be interpreted as normatively requiring that the directive-qualifier have this value for *<b>all</b>* directive-identifiers.</span>
<br>
<span style="font-family:"Calibri",sans-serif"> </span> <br>
<span style="font-family:"Calibri",sans-serif">Elsewhere in the SFW, where extension elements are added in (name: value/qualifier) pairs, the value/qualifier specification is conditional on the value of the “name”. I recommend that this be used here by changing
the current wording to:</span> <br>
<span style="font-family:"Calibri",sans-serif">“For the ‘reset’ (</span><span style="font-family:"Courier New"">directive-identifier</span><span style="font-family:"Calibri",sans-serif">) directive, the
</span><span style="font-family:"Courier New"">directive-qualifier</span><span style="font-family:"Calibri",sans-serif"> shall identify the
</span><span style="font-family:"Courier New"">next-data-id</span><span style="font-family:"Calibri",sans-serif"> parameter value …”.</span>
<br>
<span style="font-family:"Calibri",sans-serif"> </span> <br>
<span style="font-family:"Calibri",sans-serif">I don’t know if there are other instances of such unconditional specifications of extension values/qualifiers, but if there are they should be modified in the same manner.</span>
