Named attribute sets apply to a literal result element or xsl:element via use-attribute-sets; sets may include other sets recursively with a cycle guard, set attributes are lowest precedence so the element's own attributes override them, and same-named attributes collapse to the last. Folded across xsl:include/xsl:import. Splits the element-building helpers into XSLTElements.swift to stay within the file-length budget.
