CONST attributes in attributes.xml file? #478

Closed prjemian closed 6 months ago

prjemian commented 2 years ago

Motivated by trying to write the bluesky RunEngine metadata into the NDAttributes here, is it possible to add a CONST type of attribute?

One use would be for a client to inject a specific metadata key:value to be found in an image's attributes (such as PVA). If the key:value is not matched, the client can skip processing of that image.

Thank you!

I changed the code a bit after the merge. The attributes did not have the correct attribute type, so that report() was giving misleading information.
