I had always thought that wholemeal flour was OK for bread, until I saw just now that Waitrose mention both strong wholemeal and plain wholemeal. Generally, you need a flour with a high gluten content (strong flour) to make what most people regard as normal bread, in order to get the springy, rubbery dough. If you use plain flour, it will tend to be more like a pastry than a bread.
Then again, that is in the UK, and I don't know if flour is described differently over where you are. E.g. I still have no idea what the USA's general purpose flour is.
