I'm not sure how I'm expected to read the value Matsunami_10X_ER_CLC_v1.0.0.czspf. I can find the attachment itself no problem, but ReadAttachment returns a ~37KB blob (!). It says the file type is "Zip-Comp", but it sure doesn't appear to be a zip archive, and why would it be?

reader->EnumerateSubset(nullptr, "Profile", [&](int index, const libCZI::AttachmentInfo& info)->bool {  
    auto attachment = reader->ReadAttachment(index);
    size_t sz = 0;
    auto data = attachment->GetRawData(&sz);
        // do stuff

    return false;       
});

The docs aren't clear here (just auto generated stuff). All I want is the ProfileName value. It appears as though these chunks of XML are just pointers to an actual file in the CZI, but really... I just want that metadata.

I realize that I can parse the XML myself, but is there a nicer/more robust way to extract the data here? You'd think it would come with the attachment info object, but I don't see it.

Just out of curiosity... If I use cziCMD to extract the attachment it adds a Zip-Comp extension. What is a Zip-Comp file?!
