Description Michael Kay 2014-12-18 20:53:40 UTC 
Arising from the review of accumulators (see bug #27273), various problems were identified with the semantics of the @applies-to attribute: in particular, it did not appear to meet its original purpose, of enabling a streaming processor to know whether or not a particular accumulator was applicable to a particular source document.

After extensive email discussion the WG decided on an alternative approach to define the relationship between accumulators and documents, based on a @use-accumulators attribute on xsl:stream, xsl:merge-source, and xsl:global-context-item.

The proposal in message https://lists.w3.org/Archives/Member/w3c-xsl-wg/2014Dec/0018.html (member-only) (plus a follow-up in 2014Dec/0019.html) was accepted by the WG, with minor changes recorded in the minutes.
