Halliday And Matthiessen (2014: 679-85):
The full range of modal assessment is shown in Table 10-6. The table indicates the different realisational domains of modal assessment, and it gives an indication of where categories of modal assessment correspond to categories of appraisal as described by Peter White and others. We have also noted assessments that may be realised as the Epithet of a nominal group. Such nominal groups serve as the Attribute of an intensive attributive relational clause with a fact as Carrier – the explicitly objective form of assessment. However, such Epithets of assessment may be assigned to things as well as to metathings: either the nominal group in which the Epithet serves is the Attribute assigned to a Carrier denoting a thing rather than a metathing, or else the Epithet is assigned directly to the Thing of the nominal group in which it serves.
