Some parts of articles are presented like lists, but not marked up as lists. Review whether it would be better to use a programatic list structure for these.

Consider WCAG 1.3.1 Info and Relationships

Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text.

and particularly Technique H48 in regards to lists.

Areas of concern:

• list of abbreviations, currently being included as comma separated values (NB could mark them up as abbreviations too, as per Support abbreviation markup #4209)
• references, currently being included as a series of paragraphs
• keywords, currently being included as comma separated values
• authors, currently being included as comma separated values (NB not all places were authors are listed are identifying them as authors other than by visual styling - so make sure list is marked up to screenreaders as being of authors) NB only in Material.
• non list content being typeset as lists #4462
