Not sure if I'll be able to call in, but here are some initial comments from a first read:

- General: Looks like the footer has a lot of extra whitespace in it?
- Section 1, Introduction
	- You jump right in to PrintJobTicket, but never introduce the semantic model (aside from the abstract) - I think it would be useful and appropriate to provide a paragraph or two (and maybe a diagram?) providing the scope of the SM and where PrintJobTicket fits.
	- Some mixed usage of PrintJob, Print Job, PrintJobTicket, Print Job Ticket, etc.
- Sections 5.x, 6.x, and 7.x: Datatypes
	- I think we do want text here
- Section 8: Print Job Ticket Elements’ Semantic information
	- Wouldn't Table 1 be better broken up into Description and Processing elements, and put near the fugures? For example, right now if I look at Figure 15 (job processing) I need to search for OutputBin within the document to find out what it means and what the accepted values are.
- Section 9: PrintServiceCapabilities
	- Table 2: There is at least one place where the capabilities element has a different name than the job ticket element (e.g. Resolutions vs. Resolution). I don't think we need to add a column, but perhaps we could add the job ticket element in parenthesis when the names don't match?
- Section 10: Simple PrintJobTicket
	- According to the semantic definition, MediaType is part of MediaCol and not a top-level element in PrintDocumentProcessing.
	- However, the current schema shows MediaType as an optional top-level element in a sequence with Media/MediaSource, which are under a choice???
	- That doesn't match the IPP definition of media, media-type, or media-source, either... Both media-type and media-source need to be in media-col for IPP, with media/media-col being mutually-exclusive (a choice in XML schema)
