22.1.2.81 phant

This element specifies the phantom object. This object has two primary uses: adding the spacing of the phantom base element e without displaying that base; and suppressing part of the glyphfor spacing considerations. [Example: In the right column below, the descender of the 𝑦 is suppressed (set to zero) while in the left column, it is shown. The presence or absence of the descender changes the shape of the √𝑦.

• Without <m:phant> √𝑦

With <m:phant>

<m:rad>
  <m:radPr>
    <m:degHide m:val="1" />
  </m:radPr>
  <m:deg />
  <m:e>
    <m:r>
      <m:t>y</m:t>
    </m:r>
  </m:e>
</m:rad>

end example]

[Note: In typography, a glyph is the shape given in a particular typeface to a specific symbol. Most scripts share the notion of a baseline: an imaginary horizontal line on which characters rest. In some scripts, parts of glyphs lie below the baseline. The descent spans the distance between the baseline and the lowest descending glyph in a typeface, and the part of a glyph that descends below the baseline has the name descender. Conversely, the ascent spans the distance between the baseline and the top of the glyph that reaches farthest from the baseline. end note].
