10.1 states that "All serialization parameters, if set, will be passed down to the serialization method that is applied to each item in the supplied sequence.". However, only nodes (excluding attributes and namespaces) are passed down to another method. If we assume serialization parameters to be ignored for all other items, this would e.g. mean that a specified "encoding" parameter would not be applied to strings, but to text nodes. Three other parameters that might need to be checked are "byte-order-mark", "normalization-form" and "use-character-maps". Maybe the easiest solution would be to use the existing "Text Output Method" for outputting the strings resulting from the adaptive serialization rules?
The WG voted to adopt the solution suggest by Christian (i.e. to use the existing Text output method to serialize strings) as detailed in the proposal in the mailing list: https://lists.w3.org/Archives/Public/public-xsl-query/2015Nov/0035.html This proposal also addresses bug 29273.
