<zeroWid> (Phantom Zero Width)

This element specifies that the phantom has zero width. The width of the contents of the phantom is not taken into account during layout. When this property is omitted, the phantom does have width (zero width is off).
example: : In the folowing example, the second radical contains a phantom of the fraction a/b. The phantom has zero width, such that only the height grows to accommodate the hidden fraction: 
<m:phantPr>
  <m:show  m:val="off"/>    
  <m:zeroDesc  m:val="on"/>
</m:phantPr>
