Dear Jason,
I have some -generted- content which is an HTML (or XHTML) in an alt-chunk. I've tried to use the enterprise version of your library but it says just "merge.altchunk.ProcessAltChunk - TODO: How to handle altChunk: text/html".
So it seems that enterpise does not do anything special with the HTML/XHTML, but the best option is that I use the xhtmlImporterClass via the convertAltChunks() method?
My task is that .docx is a mix of .docx ...
