-/**
- * SECTION:element-proxysink
- *
- * Proxysink is a sink element that proxies events, queries, and buffers to
- * another pipeline that contains a matching proxysrc element. The purpose is
- * to allow two decoupled pipelines to function as though they are one without
- * having to manually shuttle buffers, events, queries, etc between the two.
- *
- * This element also copies sticky events onto the matching proxysrc element.
