example of MDITA specialization for survey respondents

Hi,  In the WriteTheDocs Slack, I have a couple of questions about what we mean by specializations in the LwDITA survey. Specifically, someone asked for an example of what an MDITA specialization might be. Would an example be creating a troubleshooting class in header_attributes so that you have a troubleshooting topic type in addition to concept, task, and reference?  Thank you,  Dana
