So according to the above, a high key image
must have:
1. A white or very light pastel background.
2. Subjects(s) dressed in white or light pastel clothing.
3. Little or no contrast.
4. Little or no heavy shadows.
5. Few middle tones."
Now for the definition one gathers from reading postings on POTN and other photo related websites. Keep in mind most of these image makers are accountants, mechanics, automobile salesmen, and school teachers, (and assorted other occupations) during the day and photographers at night and on weekends. A high key image is any image with white in it. It usually has a white background and overexposed skin tones. I base this on the images posted in the above thread. So in my opinion while your image has a white background and white clothing, it is overexposed, so it is a high contrast image not a high key image. It is beautiful however. Hope this helps.

I'll have to disagree that list just based on your own quotes. This is mostly because you described them as must have. The first 2 in your list are not requirements in a high key image. They are personal preferences for certain photographers, like wedding photographers for example where there can a good number of whites and pastels particularly in the brides party.
These three are consistent with each other and with the film definition and are probably the most accurate especially when referenced against each other and the actual definition found in the other quotes.
From DIY Photography.net. "To create a high key image you need to set your exposure levels to a high degree but watch out not to overexpose. High key images lack contrast and also there is a lack of shadows in the picture."
About.com Photography says, "High key pictures [can] contain small areas of dark tones, for example in the iris of the eyes in a portrait."
New York Institute of Photography Dictionary of Photography says under High Key: "A photograph made up entirely of tones above the middle tone with no heavy shadows."
The Norman Phillips and Kenneth Hoffman quotes lean toward what is the ultimate high key or how high can be achieved NOT that those elements are necessarily required. The "definitive definition of the photographic term high key" in the Norman Phillips quote describes something that can can be described as high key as in it falls in that category. This is backed up in the last sentence where high key is actually defined in that same quote, "High key exists wherever the predominant tones in the image are somewhat brighter than the middle key." and this also falls in line with the second sentence of your last quote, "A photograph which contains large areas of light tones with few middle tones or shadows" as well as the first three that I quoted.
So even just based on your own quotes (and even not being a full time photographer) it's easy to tell your list and some of the comments are opinions of ultimate/extreme high key, not necessarily the just actual definition.
