The PageLevel simple type is a signed integer that specifies the indentation level of a page in a page series. This value MUST be from "0x00000001" through "0x00000003". A value of "0x00000001" specifies no indentation. A larger value specifies increased indentation. The indentation level for the first page in a page series MUST be "0x00000001". By default, a page is not indented.
