Tricky tremolo tuplets

Hi everyone,
I am facing an issue with tricky tremolo tuplets. I've attached a screen shot of the score. Time signature is 9/8.
Thank you for your help.

Hi, I something .....
I've created a tuplet of 6 as below :

        <Tuplet id="1">
          <bracketType>2</bracketType>
          <normalNotes>6</normalNotes>
          <actualNotes>6</actualNotes>
          <baseNote>16th</baseNote>
          <Number>
            <style>Tuplet</style>
            <text>6</text>
            </Number>
          </Tuplet>
        <Chord>
          <Tuplet>1</Tuplet>
          <dots>1</dots>
          <durationType>quarter</durationType>
          <Note>
            <pitch>69</pitch>
            <tpc>17</tpc>
            </Note>
          <Tremolo>
            <subtype>r16</subtype>
            </Tremolo>
          </Chord>

Then I changed the 6 into a 9 as below :

<Tuplet id="1">
          <bracketType>2</bracketType>
          <normalNotes>9</normalNotes>
          <actualNotes>9</actualNotes>
          <baseNote>16th</baseNote>
          <Number>
            <style>Tuplet</style>
            <text>9</text>
            </Number>
          </Tuplet>
        <Chord>
          <Tuplet>1</Tuplet>
          <dots>1</dots>
          <durationType>quarter</durationType>
          <Note>
            <pitch>69</pitch>
            <tpc>17</tpc>
            </Note>
          <Tremolo>
            <subtype>r16</subtype>
            </Tremolo>
          </Chord>

It seems that it works. May be it's better to send you the files.

P.S. I may have found a bug in M.S. depending on how you look at it regarding the attempt at recreating these.

If you use a 9th-tuplet of sixteenths on a half-rest in 9/8, everything seems ready to work fine. Now make sub-divided tuplets inside of this tuplet by making a dotted-quarter rest be three-eighths, and the remaining dotted 8th be six-sixteenths. The first sub-tuplet can recreate the dotted trems just fine as with the score, but the sub-six tuplet won't allow the user to utilize dotting, even though there seems to be at face value no reason for this limitation, i.e., there can be two sets of an 8th+16th in this sub-six tuplet, but there can't be doted 8ths in it! Why not? I wonder if this is a bug or if there's a logic to it that can be described by someone in the know? If this could be dotted, then recreation of the OP's score would work fine with the addition of hidden sub-tuplets (at least in theory this would be one way of doing it).

A screenshot for some visual information:

Found a visually acceptable solution:

This utilizes hidden rests in the 9-tuplet so that there's a dotted eighth, then a dotted eighth rest that is middle-beamed and hidden, then another dotted-eighth note, then given the tremolo. Of course this disables accurate playback, so it's only a visual solution.
