As per syntax defined in the book Project Oberon 2013 and the comment above

    TextSection = ident header {char}.               # ident = TextTag
    header = type offset run {run} null length.    # type = “1"
    run = font [name] color offset length.

the “1” stands for the “type” field, which is supposed to by a “type discriminator”.

However, there is no “1” in the actual file. I.e., it’s just not implemented
in PO 2013. Note: It wasn’t implemented in Ceres-Oberon either.
