Header

The header has the following syntax:

\rtf <charset> \deff? <fonttbl> <filetbl>? <colortbl>? <stylesheet>? <listtables>? <revtbl>?

Each of the various header tables should appear, if they exist, in the above order. Document properties can occur before and between the header tables. A property must be defined before being referenced. Specifically:

The style sheet must occur before any style usage.
The font table must precede any reference to a font.
The \deff keyword must precede any text without an explicit reference to a font, because it specifies the font to use in such cases.
