Thread:Project:Support desk/Are extension tags inline or block tags?

Below is what I think, I've figured out about extension tags so far. Correct me if any of this is wrong, please! And do tell me if you can think of other tags - no matter how exotic - that you'd add to the list below, please!

Most parser tags seem to be either inline or block tags - very much like in HTML. e.g. is an inline tag while  is a block tag. But there are some tags that seem to be neither - specifically the ones that are related to transclusions:


 * and
 * and
 * and
 * and

These tags may contain both inline and block tags and may be found within both inline and block tags. They may even be found where HTML does not allow any tags at all - such as between  and

Can anybody confirm this observation?
