There are already other questions regarding compound names (noun + noun) and now I better understand the general rule, which seems to be, unless dealing with an exception, to only make plural one of the names, usually the last. I encounter is how to be more specific and convey the actual meaning, particularly in cases where there are no preceding articles or objectives. for example the sentence
please find figure descriptions in section 4
This should be the correct form. But how to convey different meanings: 1. There could be many descriptions for one figure 2. There could be many descriptions for each of many figures 3. There could be one description for each of many figures
So the example above can be misleading or ambiguous. I am interested in the formal use in books or scientific articles. Again, this might have been in telegraphic sentences where the number of words as to be kept to a minimum.
