<div dir="ltr">Here is a note from Perry from Sept 2015 to the MEI-L mailing list about this topic:<br><br><span style="font-size:11pt;font-family:"calibri","sans-serif""> </span>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"calibri","sans-serif"">Line is the appropriate entity. I can hear the sighs now, but the <span class="m_6204305444615194945gmail-il">ligature</span> element in <span class="m_6204305444615194945gmail-il">MEI</span> is not intended for these <span class="m_6204305444615194945gmail-il">brackets</span> – “The <span class="m_6204305444615194945gmail-il">ligature</span> element should not be used for <span class="m_6204305444615194945gmail-il">brackets</span> in modern notation that indicate notes that were part of a <span class="m_6204305444615194945gmail-il">ligature</span> in the original source.” (from the description of <span class="m_6204305444615194945gmail-il">ligature</span> in the schema) and so it’s currently in the <span class="m_6204305444615194945gmail-il">MEI</span>.mensural module – it disappears when <span class="m_6204305444615194945gmail-il">MEI</span>.mensural is not invoked. Creation of a similar entity for CMN or merging of <span class="m_6204305444615194945gmail-il">ligatures</span> in both repertoires is a possibility, but the topic needs discussion.</span></p>

<p class="MsoNormal"><span style="font-size:11pt;font-family:"calibri","sans-serif"">Currently, a line can only be positioned relative to the objects referenced by its @startid and @endid attributes using @start(ho|to|vo) and @end(ho|to|vo). But, I don’t think there’s any reason not to allow @tstamp, @tstamp2, @staff, @layer and @place. Even so, I think the best (that is, most precise) way to position lines is by associating them with specific events or time stamps. The @staff, @layer, @place attributes can only be useful for making sure the lines associated with a particular staff are considered when processing that staff’s data, for instance when rendering a single staff (e.g., part extraction).</span></p>

<br>
You've (perhaps unknowingly) stumbled on one of the core tenets of MEI -- the separation of the semantic and the symbol.<br>
<br>
In MEI, you wouldn't encode the brackets; you would rather encode the function of the brackets, and leave it to a renderer to deal with adding the brackets around it.<br>
<br>
There are many 'semantic' places where you may see a bracket ('semantic' here is in reference to the function of the encoding in describing intent, rather than describing appearance). You could, for example, use elements such as 'supplied,' 'sic/corr', or 'orig/reg' to describe why the accidental should be drawn in brackets in an MEI-aware renderer.<br>
<br>
The same applies to your ligature question. You wouldn't place a line above a staff in MEI to indicate a ligature; you would instead find a way to encode the grouping of these notes into a ligature. It will then be up to the renderer to display that with a line above.<br>
