Thanks, Sergey. I added you
<sergey.nozhenko@logrusglobal.com <mailto:sergey.nozhenko@logrusglobal.com>>
to the list, you can now post directly. 

Again I think this is a general XLIFF 2.x problem, to be addressed by all XLIFF 2.x implementations. With overlap this is no issue since we want a sequence of nodes, not an XML tree. I changed my implementation (see the links below. 
 
input, now including your example
https://github.com/fsasaki/its20-extractor/blob/master/sample/xliff21sample/inputfile.xml
and new output
https://github.com/fsasaki/its20-extractor/blob/master/sample/xliff21sample/output-inline-annotation.xml
and the adapted XPath at
https://github.com/fsasaki/its20-extractor/commit/7fd5f04868aad6f788fd5c4850fa26ad996cee7f
in tools/datacategories-2-xsl.xsl.

Let me know what you think.

Best,

Felix

I updated my implementation with an XPath expression that has a larger search space than the previous one. The new expression searches for the corresponding em tag in the following nodes that have the same parent node type (e.g. all source elements or all target elements).

Maybe we should add to the ITS module the constraint that extends general ITS processors: if the selected element is XLIFF sm, apply the ITS information to the next                                   em which corresponds to sm, via the startRef attribute. This would be a small burden on the ITS processors, but would greatly simply the creation of the ITS/XLIFF rules file.
