list: list

The list relation is used for chains of comparable items. Web text often contains passages which are meant to be interpreted as lists but are parsed as single sentences. Email signatures in particular contain these structures, in the form of contact information: the different contact information items are labeled as list; the key-value pair relations are labeled as appos.

In lists with more than two items, all items of the list shoud modify the first one.

Steve Jones Phone: 555-9814 Email: jones@abc.edf
name(Steve-1, Jones-2)
list(Steve-1, Phone:-3)
list(Steve-1, Email:-5)
appos(Phone:-3, 555-9814-4)
appos(Email:-5, jones@abc.edf-6)

In an itemized or numbered list, we have been taking the item marker as a dependent of the head of the contentful list item. This appears to be better than the alternative.
