Data source rephrasing and clarification

Byte production requests and delivery of newly produced data don't need to
1-to-1 correspond. Tried to use non-misleading expression.

 				A data source produces the bytes to be consumed via the <a>ReadableByteStream</a> interface instances.

+						Accepts requests for production of bytes from a <a>ReadableByteStream</a>. A byte production request consists of an integer indicating the number of bytes to produce in addition to already requested ones.
 						Interpretation of the request is up to data sources.
