RE: ISSUE-189: do regions scroll their flowed content? [DFXP 1.0]

You would want to set the region to tts:displayAlign=’after’ so that the later added lines have the effect of pushing the earlier lines out of the top. The br
S are un-necessary here as we have an implied line break because of the p. One could do the same thing with spans and br.

Then to do a multiple scrolled region:

<.div region=’afterformattedregion’>

<p begin=”1s” dur=”3s”>first line</p>

<p begin=”2s” dur=”3s”>second line</p>

<p begin=”3s” dur=”3s”>third line</p>

<./div>

By way of example so we’re clear on the timed flow, the following TTML into a 2-line-height region:

<p begin=”1s” end=”3s”>first line</p>
<p begin=”2s” end=”4s”><br>second line</p>
<p begin=”3s”><br>third line</p>

Would result in the following text over the time periods shown:

1s-2s:
first line
<blank line>

2s-3s:
first line
second line

no; the <br/> would result in the second <p> would produce

first line
blank line (from <br/>)
second line

so visually you would have

first line
blank line


3s-4s:
second line
third line

no, the <br/> would produce a blank line before second line, so visually you would have

blank line
second line
[not visible blank line]
[not visible third line]

etc

why you are inserting <br/>?
