During eXtyles Activation you may have received the following warning and been unsure what to do:
WARNING: The following styles have an illegal character, '<','>', or '"': 'NormalChapter C"'
Click YES to rename styles and continue. Click NO to exit this process
eXtyles cannot process documents with style names containing the characters <, >, or ". During activation, eXtyles runs a quick check for incompatible style names and offers to rename them for you (as eXtylesStyle1, eXtylesStyle2, etc.). This renaming completely resolves the issue, and so we recommend that you click YES if this warning dialog appears.
If you would like to avoid this warning, consider eliminating these three characters from any style names in templates you use for document composition.
