Which opportunities to add more mixin properties to a node if jcr:mixinTypes already defined

[Ulrich <Fo...@gombers.de>]

I need to add additonal properties to the nt:file-nodes. I know I can do this by
definining the properties to a mixin node type and then defining this new mixin
node type to the node(s) by the Property jcr:mixinTypes.
But then I loose the opportunity to expand/change this. According to the
JCR-Specs "6.7.5 Special Properties jcr:primaryType and jcr:mixinTypes", the
property jcr:mixinTypes cannot be deleted or changed any more; this is, I even
cannot add additional nodeTypes to the multi-value array of the
jcr:mixinTypes-property.

I think this may really become a big problem in the future - I'm not aware what
might arise which also needs additional properties added to the node and would
be interested if there are known solutions for this

That point only refers to using methods like setProperty() to modify
the values of these properties. You can still use addMixin() and
removeMixin() to modify the set of mixin types associated with a node.
