Should the "Types of properties" table have a row (line) for property type "Text"?

[Jaime]

There is a "Types of properties" table at
https://lilypond.org/doc/v2.25/Documentation/learning/types-of-properties
and it does *not* have a row (line) for the property type "Text". Yet
https://lilypond.org/doc/v2.25/Documentation/learning/modifying-context-properties
says that the type of the property that has the name "instrumentName"
is text. Does this mean that the "Types of properties" table is
missing this row (line)?

(I've just realised that it doesn't contain a row for "real" either,
but perhaps "real" is a synonym for "number".)

TIA, Jaime.
