position from above the notes to below – that is, where the slur intersects the melodic line, so to speak. I guess that the use of @bezier will give the desired result in most situations, but as the actual rendering of the slur must be dependent to some degree
on other factors such as the note spacing or system breaks, I wonder how we can be sure that it will always cross the melodic line at the desired place. With @bulge or @curvedir (with extended values as suggested by Zoltan) this must be even more uncertain,
right? In principle, a rendering algorithm may draw the slur in Benni’s example above the first three groups of notes and below only the last group when using @bulge or @curvedir. How do we avoid that?<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:65.2pt">Hi Perry, <o:p></o:p></p>
<div>
<p class="MsoNormal" style="margin-left:65.2pt"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:65.2pt">I think extending the data type of @curvedir attribute could be justified simply base on the argument of classification: @curvdir provides a classification mechanism, but this classification is rather incomplete,
the current values of @curvedir do not cover all the cases that are out there (see Benni's example: nor "above" neither "below" is appropriate, and the omission of the attribute surely cannot imply what we want to convey, that is the curve goes also above
and below). This has nothing to do with rendering, since in order to render a slur or phrase mark, the actual curve needs to be calculated anyway, even when "above" or "below" is applied.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:65.2pt"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:65.2pt">Out of Benni's suggestions I quite like "above-below" / "below-above". (Note that his question concerns @curvedir not @place.) In fact, it occurs to me, we could even allow an alternating sequence of the values
"below" and "above". Benni's example would be encoded as <slur curvedir="above below"/>. This, beside conveying the fact that the curve goes first below, then above, could also be applied to curves with multiple inflection points. I have no literary example
for this at hand, but wouldn't be surprised if there was some in existence.<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-left:65.2pt"><span style="font-family:"Arial Unicode MS","sans-serif";color:black">The place attribute is for describing the placement of an entity in general terms. For phrase marks and slurs, it also generically describes
the curvature of the mark, and therefore functions as short hand for a more detailed description given by the bulge or bezier attributes. It would be possible to add a value to @place for slurs/phrases with multiple inflection points, such as "mixed" or perhaps
"complex", but this would only fulfill a classification purpose -- it wouldn't provide any information regarding how to draw the slur/phrase. So, one would still need to use @bulge or @bezier for rendering.<o:p></o:p></span></p>

<div>
<p class="MsoNormal" style="margin-left:65.2pt"><span style="font-family:"Arial Unicode MS","sans-serif";color:black"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:65.2pt"><span style="font-family:"Arial Unicode MS","sans-serif";color:black">Another complicating factor is that @place is used by a number of elements other than slur and phrase. Adding "mixed" directly to @place would
introduce the possibility of nonsense in the case of, say, <accid> or <breath>. Of course, a specialized form of @place for slur/phrase is a possibility, but would need careful handling.<o:p></o:p></span></p>
