It looks as if a stylesheet specifying *:x or x:* in an xsl:strip-space or xsl:preserve-space declaration will fail on import. The value is serialized as Q{uri}* or *:x respectively, but the package loader attempts to parse the value as an ItemType (which it is not).

Test merge-002 uses xsl:strip-space elements="*". XJ exports this as element() and succeeds in importing this using parseItemType(). But XX exports it as *, which is not accepted. I haven't found any tests using *:x or x:*.
