[MEI-L] pointing mechanism

[Andrew Hankinson]

xinclude will essentially create a single serialized XML file from a number of files, so no, you can’t have duplicate IDs.

One solution we’ve used before is to have automatically-generated UUIDs. They’re a bit cumbersome, but it’s almost impossible to generate two of the same. An XML ID must start with a letter, though, so I generally prefix the UUID with “m-“.

I could rely on referencing from a section element, but I wonder why I cannot do it from higher level ones?

I'd assume if it is generic, it would be allowed everywhere where it is not impractical, but their use seem to be a lot more restricted. Why is that?
