text: The members of the**DocExComment_BeginTextRun**structure are as follows: 
  
  **Ident**Specifies the constant value, msodocexsignature, which identifies this EMF 
  
  comment as containing semantic information. 
  
  **iComment**Specifies the MSODOCEXCOMMENT value, 
  
  msodocexcommentBeginTextRun. 
  
  **lcid**Specifies the LCID for the text sequence. 
  
  **cGlyphIndex**Specifies the size of an array that follows this structure. This array 
  
  implements a glyph index table that maps Unicode code points in the actual text 
  
  to the corresponding glyphs in the EMF. Each element of the array corresponds to 
  
  a code point in the text. The value of that element specifies the first glyph used to 
  
  render that code point in the EMF. Two or more adjacent code points may have the 
  
  same value in the array, which means that they both resolve to the same glyph. 
  
  The value can also be**0**, which means that this code point does not map to any 
  
  glyph. 
  
  **cwchActualText**Specifies the size of the sequence of Unicode code points that 
  
  follow the glyph index table. This is the text that a consumer of the document can 
  
  use for searching, copying/pasting, and accessibility. The value of this member can 
  
  be**0**, which means that no Unicode text is provided.
