Generating a file with altChunks

[osdiab]

Word has this feature called altChunks for patching together various documents into a single Word document. My company has been trying to find good ways of converting HTML documents created with a WYSIWYG editor in our web app, to come out nicely in Word. We use the CloudConvert API today but it has some erratic behavior around the output; so this came up as a possibility for a way for us to do this type of conversion.

I'm curious if there's a way to use this library to insert an altChunks block into the generated XML, including if there's a way we can e.g. make some sort of plugin or custom logic assuming it doesn't exist somewhere in the library already. In the meantime we'll do a little experimenting to see if this functionality even works properly according to our expectations. Thanks!
