You could say,
items include but are not limited to [list].
Or, at some point before or after the list, you could simply say,
this list is not comprehensive.
EDIT: I realise that I haven't really answered your question, sorry!
I think the phrase this list is short of being exhaustive conveys that almost all the items are included, or at least all the relevant ones, so if that's what you mean to say then by all means use it. You could add some further explanation: ... but includes all the salient points, for example.
As stated in one of the comments, this list is anything but exhaustive conveys that the list is far from complete, and emphasises that it should not be relied upon as to the complete content of the list.
