LanguageId deprecated in favor for new properly named property 'locale'

The content schema of Headless Server contained the property 'languageId' but was not mapped properly to a property in content objects, thus delivering always null. The property is now deprecated in favor for the newly introduced property 'locale', which maps to the corresponding property of localized content objects. Additionally the now deprecated property 'languageId' was mapped to 'locale' in order to fix the always null issue.

Headless supporting queries for localized variants of content objects

Starting with version 2010.1 headless features the ability to query for localized content objects of any localizable content and derived sites of a site object. With the new abilities it is now possible to develop more generic clients, e.g. being able to bootstrap a client for all derived sites or to crosslink to localized contents.
