The is no "current" region, just the anonymous generated region. If an
extent/origin were specified on tt:p, then other styles specified on tt:p
that apply to region (but not tt:p) would also be assigned to that region.

Otherwise, style inheritance would work exactly as defined in 8.4.2.

Specifically, if one had something like:

<div region="r1">
  <p tts:extent="..." tts:origin="...">Text that doesn't go in r1, but goes
into an anonymous region</p>
</div>

In other words, it would work just as if one had specified:

<region id="r2">
  <style extent="..."/>
  <style origin="..."/>
</region>
...
<div region="r1">
  <p region="r2">Text that doesn't go in r1, but goes into r2</p>
</div>

The current language in 9.3.2 already handles this case.
