Structured Elements in Text Boxes
When my department converted our FrameMaker document from unstructured FrameMaker to structured FrameMaker (using a variant DocBook EDD), one of the challenges was how to handle a large number of FrameVector graphic that use multi-line text boxes. I ended up structuring the text in these graphics, because it seemed that was the only way to produce documents that could be validated (Text boxes needed to be structured)
1) save each frame vector graphic containing structured elements as a separate file
2) import each of these graphic files by reference AND set the import option to "Retain Sources Formatting"
Using this method, the files retain their structure, the book validates completely, and all of the graphics are processed without corruption by Web Works ePublisher Pro 2008.3.
