/**
 * ### Condition: Is context Backend?
 *
 * A condition ViewHelper which renders the `then` child if
 * current context being rendered is BE.
 *
 * ### Examples
 *
 * ```
 * <!-- simple usage, content becomes then-child -->
 * <v:condition.context.isBackend>
 *     Hooray for BE contexts!
 * </v:condition.context.isBackend>
 * <!-- extended use combined with f:then and f:else -->
 * <v:condition.context.isBackend>
 *     <f:then>
 *        Hooray for BE contexts!
 *     </f:then>
 *     <f:else>
 *        Maybe FE, maybe CLI.
 *     </f:else>
 * </v:condition.context.isBackend>
 * ```
