Changes for 3.x version

I’ve noticed some things we can do when we decide to make a 3.x version which will allow us to have breaking changes. I’ll keep this list up-to-date with ideas as we come across them:

• OpenXmlSimpleType.TextValue should be made private protected
• Types derived from OpenXmlSimpleType should not have implicit casting operators if they allocate objects
• Make EnumStringAttribute internal
• Consider making a DocumentFormat.OpenXml.Validation library that adds the validation logic. This currently adds a few megabytes to the openxml library
• Redesign usage of IFixedContentTypePart; possibly remove
• Remove obsolete classes/methods
• Slim OpenXmlPackage (and maybe others) by moving some helper methods to extension classes. An example is the FlatOPC methods
• Make ValidatorSettings public and readonly. Add a constructor to OpenXmlValidator to handle the settings
• Consider breaking up library into smaller ones for Word/Powerpoint/Excel.
• Add standard unit conversion type. There are different units such as points, emus, etc. that could be understood and convertible from the api.

Do you have a another place for feature request discussions? I want an SaveAsPDF feature. (On Linux)

Another one from me: break up the monolithic library into separate ones for Word, Powerpoint and Excel.
