Module vml 

VML (Vector Markup Language) support for Excel legacy comment rendering.

Excel uses VML drawing parts (xl/drawings/vmlDrawingN.vml) to render comment/note pop-up boxes in the UI. This module generates minimal VML markup for new comments and tracks preserved VML bytes for round-tripping.

Functions

build_vml_drawing

Build a complete VML drawing document containing shapes for each comment cell.

extract_vml_comment_cells

Extract comment cell references from an existing VML drawing XML string.
