check for errors - validation of number of subtags

[Bogiegit]

Tags should be checked in terms of minimum/maximum number of subtags

some samples:

• Tag 'CAUS' may only appear 1 times under tag 'DEAT'
• Tag 'DATE' may only appear 1 times under tag 'BIRT', 'DEAT', 'MARR'
• Tag 'NICK' may only appear 1 times under tag 'NAME'
• Tag 'PLAC' may only appear 1 times under tag 'OCCU'
• Tag 'TYPE' may only appear 1 times under tag 'EVEN', 'MARR', 'NAME'

This is a double-edged sword... Sometimes you would want to document contradictions by using the same subtag twice with the first one being the preferred one. Nevertheless it would be nice if webtrees showed a warning, not necessarily an error.

I do not think that is permitted. You can enter multiple facts/events - but not lower-level attributes.

For example, if you had two contradictory INDI:DEAT:CAUS, then you would need two INDI:DEAT events

Good point - thanks!
