block with keep-together.within-line="always"

Hi XSL experts,

What should happen when a block with
keep-together.within-line="always" has text which is longer than one
line?  Should the text wrap?

For example the following flow:

<fo:flow flow-name="xsl-region-body" line-height="1.2em"
font-size="10pt" font-family="Times">
    <fo:block keep-together.within-line="always">
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Duis
ullamcorper fringilla ligula. Donec cursus, justo quis dapibus
vehicula, erat lacus faucibus mi, vel accumsan nibh arcu at sem. Sed
adipiscing gravida lectus. Suspendisse non nunc id justo consectetuer
aliquam. Vivamus.
     </fo:block>
</fo:flow>

The spec says keep-together.within-line "...imposes a keep-condition
.... with context consisting of the line-areas".  And since a
line-area, according to the spec, is a "special type of block-area" it
seems to me that the text should wrap.

Your thoughts?

Thanks,
John
