<p dir="ltr">Quick question: how would you encode a chord where only some notes have a dot? </p>

Chords containing a mixture of dotted and undotted notes have been observed in the music of Bartok and Brahms; they surely occur in other composers. The essential point is that chords can contain notes with any mixture of durations.<br>

> <dot> within <chord>, however, is a completely different problem. It seems to me that chords are never dotted, only the notes within them. It is true that @dots is allowed on <chord>, but it was placed there as a convenience. However, one cannot extrapolate from its existence the need to allow <dot> within <chord>. As Jo has already noted, allowing <dot> within <chord> introduces unnecessary complexity and ambiguity, so I advise against that approach.<br>

> Again, there is redundancy between the @dots attribute on <note> and the <dot> element, but they serve different purposes -- @dots exists in the logical domain and <dot> exists in the visual one. The <dot> element is providing additional information not communicated by the @dots attribute, not supplanting it.<br>
><br>
> It’s often difficult to draw a bright line between the logical and visual domains. As a general rule, however, when there is only one “source of information”, such as note/@dots, then it functions in both domains. The addition of another “source”, such as note/dot, separates the domains. In other words, the visual domain can often be surmised from the logical, but making it explicit requires extra information; that is, usually elements. (BTW, the gestural domain can also be inferred from the logical/visual, but making it explicit also requires additional information, usually attributes.)<br>
