Native File Parser with Segmentation

Dear community,

In a custom File Filer, I am using a Sdl.FileTypeSupport.Framework.NativeApi.INativeExtractionContentHandler to Output structure tags 

[..]
Output.StructureTag(structureTagProperties);
[..]

and then the text to be translated

[...]
ITextProperties textProperties = PropertiesFactory.CreateTextProperties(child.OuterXml);
Output.Text(textProperties);
[...]

While the text is correctly extracted, Studio does not segment the texts further - so basically paragraph-based segmentation is enforced, even when the TM is set to sentence-based segmentation during convert and copy batch tasks.

How can I extract text in such a way that the Trados text segmentation will still take place?

Best wishes,
Simon
