 Van der Sandt (1992) proposes that presuppositions whose descriptive content is relatively poor are hard to accommodate. This generalization is borne out by pronouns, names, and semantically attenuate definite NPs like “the person”. However, it is not very clear what “relatively poor” means. Definite NPs like “the water molecule” or “the lonely carpenter” don’t strike us as particularly poor, but may be hard to interpret by way of accommodation. Similarly, the presuppositions associated with “too” may be quite rich, and nevertheless they are generally hard to accommodate. Geurts and van der Sandt (2004) propose to account for the latter by adopting Heim’s (1992) idea that the presupposition triggered by “too” contains a pronominal element, which blocks accommodation, but this proposal has been criticised by Beaver and Zeevat (2007). Be this as it may, it seems clear that van der Sandt’s generalization cannot be read as biconditional: even if poor presuppositions are difficult to accommodate, the reverse doesn’t always hold.
