[The following is extracted from the liaison received from SMPTE at https://lists.w3.org/Archives/Member/w3c-archive/2012Sep/0214.html]

See "Drop Shadow character style" above, Section 6.4.13 at ST 428-7 and Section 8.2.20.

It shall be possible to specify whether drop shadow and outline effects applied to a <span> element are feathered or not, for the purpose of smoothing the effect.

The feathering shall be applied linearly through the entire effect thickness. Maximum feathering shall be on the edge of the shadow or outline, and minimum feathering shall be at the edge of the character.
