HTTP Headers for HTTPConnector in Script Based Value Set Provider

Hi everyone,

I saw this very good blog entry about using script based value set providers for querying remote resources
in javascript using the HTTPConnector:

http://jorgediazblog.wordpress.com/2012/06/27/work-item-customization-httpconector-and-oauth-in-rtc-4-0-for-oslc/

So the essence of this connector lies in the following class which can be found in the RTC SDK:
com.ibm.team.workitem.api.common.connectors.HttpConnectorParameters();

Inside the following parameters are defined:

//url: null,

    //xpath: null,

    //columnXpaths: null,

    //columnIds: null,

    //formBasedAuthenticationLoginURL: null,

    //formBasedAuthenticationUsernameInputName: null,

    //formBasedAuthenticationPasswordInputName: null,

    //credentialsId: null,

    //useBasicAuthentication: null,

    //useFormAuthentication: null,

    //useOAuth: null,

    //userName: null,

    //password: null,

    //ignoreInvalidCertificates: null,

    //log: null

Question: Where can I set HTTP headers?
This would be a very powerful feature. One example would be setting a content-type of "application/rdf+xml" and then just using the full capabilities the OSLC REST API gives you in terms of querying and selecting resources.
