+ * <code>
+ * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:
+ *
+ * There are a number of formatting codes that can be written inline with the actual header / footer text, which
+ * affect the formatting in the header or footer.
+ *
+ * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
+ * the second line (center section).
+ *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
+ *
+ * General Rules:
+ * There is no required order in which these codes must appear.
+ *
+ * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
+ * - strikethrough
+ * - superscript
+ * - subscript
+ * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
+ * while the first is ON.
+ * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
+ * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
+ * order of appearance, and placed into the left section.
+ * &P - code for "current page #"
+ * &N - code for "total pages"
+ * &font size - code for "text font size", where font size is a font size in points.
+ * &K - code for "text font color"
+ * RGB Color is specified as RRGGBB
+ * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade
+ * value, NN is the tint/shade value.
+ * &S - code for "text strikethrough" on / off
+ * &X - code for "text super script" on / off
+ * &Y - code for "text subscript" on / off
+ * &C - code for "center section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the center section.
+ *
+ * &D - code for "date"
+ * &T - code for "time"
+ * &G - code for "picture as background"
+ * &U - code for "text single underline"
+ * &E - code for "double underline"
+ * &R - code for "right section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the right section.
+ * &Z - code for "this workbook's file path"
+ * &F - code for "this workbook's file name"
+ * &A - code for "sheet tab name"
+ * &+ - code for add to page #.
+ * &- - code for subtract from page #.
+ * &"font name,font type" - code for "text font name" and "text font type", where font name and font type
+ * are strings specifying the name and type of the font, separated by a comma. When a hyphen appears in font
+ * name, it means "none specified". Both of font name and font type can be localized values.
+ * &"-,Bold" - code for "bold font style"
+ * &B - also means "bold font style".
+ * &"-,Regular" - code for "regular font style"
+ * &"-,Italic" - code for "italic font style"
+ * &I - also means "italic font style"
+ * &"-,Bold Italic" code for "bold italic font style"
+ * &O - code for "outline style"
+ * &H - code for "shadow style"
