What does <value> tag represent in the Flags XML? #123

I'm writing a timeline application where I show a video and overlay captions. I want another app to build my XML transcript and then I'll fire this into my timeline app so the captions appear at the right time. This all makes sense but I don't understand what the value represents in the flag xml?

I add the flag track by doing

timeline.addFlags("caption");
ofAddListener(timeline.events().bangFired, this, &testApp::receivedBang);

If I edit the xml file myself and set the value to be 1.0000000 nothing seems to break. But if I add a flag within timeline editor this value appears random. What does this value represent?

<keyframes>
<key>
<flag>hello</flag>
<time>00:00:02:504</time>
<value>1.000000000</value>
</key>
<key>
<flag>World</flag>
<time>00:00:04:504</time>
<value>1.000000000</value>
</key>
</keyframes>
