seo - Schema.org memberOf error -

this problem's driving me crazy sec day in row. so, problem: i'm trying utilize "memberof" property "organization", , google structured info tool there error:

error: page contains property "memberof" not part of schema.

at same time schema.org says, property of "organization":

http://schema.org/memberof

if alter "organization" "programmembership", no more errors, good. problem need utilize organization.

the code i'm trying run on google tester:

class="lang-html prettyprint-override"><div itemscope itemtype="http://schema.org/organization"> <div itemprop="name"> name <div itemprop="memberof" itemscope itemtype="http://schema.org/organization"> <div itemprop="name"> name2 </div> </div> </div> </div>

you can ignore error. utilize of microdata , schema.org valid.

the google structured info testing tool not up-to-date (it has same problem license property), maybe because allowed values of property changed "recently" (couldn’t find it, guess).
