    THe old version had ’paragraph 33’ of DHKS as a reference. I changed it to page 23, which gives the definition. (Paragraphs are not numbered as such in DHKS, although one could refer to the subsections as paragraphs which seems, to me, a bit confisuing. Subsection 33 is on the topic but starts on page 96.)

    edited Definition 2 (following DHK 33.1) so that Remark 3 does not appear circular.
