[O] Tags v. PROPERTIES for noexport and ignoreheadings

[Ken Mankoff]

Hi List,

I'm trying to figure out when I should be using tags and when I should be using 
properties, for the cases of "noexport" and "ignoringheading".

I think I began using Org before either of these features were supported. Then 
people provide code snippets that added this functionality based on tags. About 
a month ago I think I learned that there is now a PROPERTY drawer keyword. I 
switched to that at the time, but now I cannot find the message that suggested 
this change, nor can I find the correct keyword I invoke (org-set-property).

Thanks,

  -k.
