I'd like to know this as well. The docx file is a download offered by MS for use and available for development.
I suppose the first answer meant to say, that the icons are only meant to be used within Office; that is with Office add-ins and such. They can be referred with Office Fluent UI definition XML for example. So the distribution form serves as visible "Ahh I want that icon in my add-in" reaction and then choosing the specified ID to use in "imageMso" attribute.
Like this (see proper full XML in Office Fluent UI customization).
I found this after a long and grueling search soltechs.net/CustomUI/imageMso01.asp.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
