The startpage markup indicates the start of a page, as determined by Arbortext Editor's formatting engine. The number attribute gives the sequential page number.
A folio may be set for the attr1 attribute. It will appear as part of the line number in the format: folio,\-\,lineno.
The type of page break to force is controlled by the attr2 attribute. Valid values are next, verso, and recto. The default is to not force a page break.
The endpage markup specifies the end of a page. If the attr2 attribute is set to the fill, then underfull errors are not reported for this page and the page is not stretched if it is short.
