HXS file format: Does public domain C or C++ source code exist that can decompress HXS help files?

Various firms use the Microsoft HXS format for compressing help files to support their products. I wish to enable users with licensed copies of HXS help files to index and search their content using my "Words Close Together" search engine. There are suggestions in the literature that Microsoft is using a standard form of compression for HXS.

[1] Is the compression method open?
[2] Does C or C++ public domain source code exist that would permit me to embed extraction capability in my indexing software?
[3] Where can I get such source code?

I don't know the .HxS format details, but if it is similar (or better, the same) as the .CHM format, then 7-Zip does support them & has source code.

Confirmed: as of v4.27beta 7-Zip has been able to extract .CHM & .HxS files (same compression).
