Print page change indicator requirements

Note, this is the indicator shown in the body of the running text when a print page change occurs.

- Print page indicators are shown at the point when a new print page occurs. This may occur between paragraphs (or other "blocks"), or mid-paragraph (inside a "block").
- (UKAAF): - Print page indicators are shown as a centred line consisting of dot 5, dots 2-5, followed unspaced by the new print page number.
- (UKAAF): New print page indicators are shown on any line of the page (except the header line).
- (UKAAF): New print page numbers are shown, even if the print and braille page turns coincide.
- (BANA): Print page indicators are shown as a full line of dots 3-6, with the new print page number unspaced at the right.
- What do other countries do?
- What CSS (extension?) can we use to govern the behaviour?
