In QuarkXPress 9 and later you can setup Bullet and Numbering Styles and then use these to build a macro type Style called an Outline Style. Q2ID will support the continuation of numbering from one section to another ONLY IF the original QuarkXPress document was created using an Outline Style. If the Outline was created using the indent values entered into each separate Number or Bullet style, Q2ID will continuously increment the Outline numbers or letters and this will yield unpredictable results.
In the example below, the original QuarkXPress document is on the left and the converted InDesign document is on the right. The original QuarkXPress file was created without using an Outline Style and just using Numbering Styles and thus yields unpredictable number results in InDesign.
