page break in markup

[Graham Percival]

I'd like to insert a page break in the middle of a long \markup section 
(or
between two separate \markup sections).  This is for a large \book; I'd 
like
to have two or three pages of text before beginning the music.

I kind-of managed to get a page break like this:
\book{
\markup{ Page 1}
\score{
{ s4 }
\header { breakbefore = ##t piece = " " }
\layout{
\context { \Staff
\remove Time_signature_engraver
\remove Key_engraver
\remove Clef_engraver
\remove Staff_symbol_engraver
}}
}
\markup{ Page 2 }
}


but somehow I don't think that this is the best solution.  :)

Cheers,
