The formatting categories a named style includes — Excel’s “Style Includes”
checkboxes, stored as the apply* attributes of the style’s cellStyleXfs
record. Applying the style to a cell only stamps the included categories.
The default (like “Normal”) includes everything; the built-in “Percent”,
for example, includes only the number format.
Represents the state of the worksheet as seen by the user. This includes
details such as the currently selected cell, the visible range, and the
position of the viewport.
Represents a hyperlink in the worksheet, which can be either external or internal.
The display text is not part of the link, it is the content of the cell the link is
attached to. Links are just cell metadata.
