The Variables panel displays the names of dynamic objects as they appear in the Layers panel. If you save the template in SVG format for use with other Adobe products, these object names must conform to XML naming conventions. For example, XML names must begin with a letter, underscore, or colon, and cannot contain spaces.

Illustrator automatically assigns a valid XML ID to every dynamic object you create. To view, edit, and export object names using XML IDs, choose Edit > Preferences > Units & Display Performance (Windows) or Illustrator > Preferences > Units & Display Performance (Mac OS), and select XML ID.
