That sounds like a good first step.

HTML + CSS for styling is, in general, not robust enough. However, if 
the chosen line breaks are available (as is the case with PDF), this 
should lead to a more robust layout, which preserves the line breaks 
even if the document is "opened for editing" and then only does the 
minimal amount of reflow that is necessary when content is added.

Best,
Tamir
