allow values "contributing" and "technical" for the @role attribute on tei:editor elements

[wlpotter]

See srophe/bethqatraye-data#79

I believe we are making this a syriaca-wide schema update, but we should discuss to make sure that is how we want to handle these attribute values.

@wlpotter I agree, let's confirm. Syriaca-wide sounds right to me but @davidamichelson should confirm.

Plus need to work out "former" editor title.

[dlschwartz]

@davidamichelson @wlpotter we have three instances of <editor role="contributor">. Do you want to change those to "contributing" and use that from here on out or do you just want to use the current "contributor"?

[dlschwartz]

FYI, see our discussion here regarding the use of "contributor." It looks like it comes from dct:contributor.

[dlschwartz]

Add <editor role="contributor">, <editor role="technical">, and <editor role="associate">

[davidamichelson]

• @dlschwartz please update the Srophe all ODD schema to permit <editor role="contributor"> in the TEIHeader (The use of <editor role="contributing"> will be in NHSL body only and is a specific case different from here).

• @davidamichelson will update the documentation to make clear the definition.

[davidamichelson]

@dlschwartz actually wait this is a mess, we shoudl talk in person :)

[davidamichelson]

Okay this is done!
