This field contains a list with the properties which must be set at
a content that was just created using
XContentCreator::createNewContent before it can be
committed (by executing the command "insert" at the new content).
This is an implementation specific string characterizing the
kind of a content (e.g. "application/vnd.sun.star.hierarchy-link").
The value of this member should match the value returned by
XContent::getContentType of an appropriate content.
These flags contain extra information on the content, like its kind
(KIND_FOLDER, KIND_DOCUMENT, KIND_LINK).
It is highly recommended to fill these flags very accurately, as
they are very important when transferring contents between different
ContentProviders.
This field contains a list with the properties which must be set at
a content that was just created using
XContentCreator::createNewContent before it can be
committed (by executing the command "insert" at the new content).
If one of the properties is missing, the insert command will fail.
In example, a new file system folder content will need a title. The
Properties member of the ContentInfo provided for this kind of
content must include the property "Title".
Important: The required properties must have one of the
following basic data types (in order to make it possible to implement
client applications with a small set of generic input methods for the
values):
