But surely every pengine process knows which meta_attributes it would
consider "valid" for a given resource class
(primitive/clone/master_slave). Would it not be possible to enumerate
them in the meta-date call, so that the GUI has more hints?

Afterall, all data is available in include/crm/msg_xml.h - could that be
changed to an array which could be dumped via pengine metadata, or to a
public .h which the mgmtd/CLI could include during build?

Clearly, being more assisting to the UIs would be helpful ;-)

One imagines that with a real parser for them, some code even could be
consolidated to check their values etc. Just thinking. Nothing urgent
;-)
