According to Braille Formats 2.9, Dedications are placed on their own page (with no other text) and should begin on line 1 or line 3 (depending on if there is a running head used or not). Your example should be treated as a paragraph 9 (either blocked or 3-1). If it were poetry, all lines would begin in cell 1.
I'm confused about the wording in Formats 2.9 - nothing there states clearly that a dedication should be the only text on a page. 2.9.1. a states that a dedication begins on a new braille page, but not that nothing else should be on the same page.
Is this defined somewhere else in the Formats?
I've come across a dedication that takes up just two lines, not even full lines, so moving the following text to the next page seems like a huge waste of space.
