'xslfo: staticcontent overlap to flow

I have an arrangement like this in scala using xslfo:

PageSequence(
   Seq(
       Fo.staticContent(....),
       Fo.staticContent(....),
       Fo.staticContent(....)
    ),
    Fo.flow(...)
)

Content of staticcontent objects may vary. It is causing staticcontent part to sometime overlap flow part.

How can I avoid this? I see static-content has no attribute for adjusting height.

xsl-fo

The allowed height of the static content comes from the extent property of the region that receives the static content.

Static content flows into one of the 'outer' regions: fo:region-before, fo:region-after, fo:region-start, or fo:region-end.

The correspondence between the flow-name property on the fo:static-content and the region-name property on the region FO determines which of the regions receives the static content: you could, for example, have the same static content that appears in the fo:region-start on left-hand pages and in the fo:region-end on right-hand pages, or you could have static content that appears only on the first page of a page sequence (when the first page uses a separate fo:simple-page-sequence).

The extent property (see https://www.w3.org/TR/xsl11/#extent) determines the height or width of the outer region.

The content of the fo:static-content can overflow its extent. For fo:region-before, it might overlap the fo:region-body, and for fo:region-after, it might overflow off the bottom of the page.

Note that fo:region-body can have margins specified so that it does not (ordinarily) overlap the outer regions.
