with the content server web service, there is a API to create a document, e.g.
documentManagementClient.CreateDocumentAsync(...);
in the returned result, there is an ID for the document. to create place holder, one would do:
documentManagementClient.CreateDocumentContextAsync();
which would return a string, assume to be contextId. it's easy to check if a document exist or not, but how to check if a place holder already existed?
Thx
