Again about the Lite documentation!
I'd some problems with understanding some parts of the text there:
1) Where it describes the use cases for the <add>, <del> (and other elements designed for editorial intervention) it says that: "These elements are not limited to changes made by ***an editor***; they can also be used to record authorial changes in manuscripts. ...", although in the description of the <add> element we can see in the Note section: "The add element should not be used for additions made by editors or encoders ...". I couldn't interpret both together!
2) Where the document is trying to introduce the <interp> element, it discusses the practice of using the <seg> element with a proper type attribute for some interpretive cases and counts two restriction on it, which the first one is the requirement that all of the elements in the marked-up text to be properly nested. Then it stated that the <interp> element doesn't have such a restriction! I think that it's can be true with the <span> element (if you use <anchor> element to mark the start and end of the span) but it's not the case for <interp> element which you should use the <seg> element (or so) to mark the text and then pointing to <interp>. Am I right? Please let me know if there is another trick for that.
3) Again, where the document is discussing the <interp> element, it states that: "Moreover, interp is ***an empty*** element, which must be linked to the passage to which it applies ...". I couldn't understand what this means (the meaning of its emptyness).
