Import precedences are assigned in post-order over the import tree, so sibling imports are distinct and every unit sits above its own imports; apply-imports searches only the current template's stylesheet's own import subtree per 5.6, reverting to the built-in rule when that unit imports nothing; an included stylesheet's declarations join the including unit at its precedence while its imports join the import list; and include/import hrefs resolve against the including stylesheet's URI. Included documents' roots stay retained until their declarations are parsed (tree parents are weak, so the in-scope xmlns chain could vanish mid-compile). Xalan baseline 159 -> 144 (reluri 11 -> 3, impincl 9 -> 2).
