Hello Juha,

why not try by yourself ? for the record, there
are 5 open-source engines listed on the W3C site:
- Fatdog's XQEngine
- GNU's Qexo (Kawa-Query)
- Lucent's Galax
- Sourceforge's Saxon
- Qizx/Open

By the way, I will be surprised if your query
works as it is:
in the where clause:  where @id = 'a'
the path expression '@id' has no initial node(s), therefore
-if I make no bloomer- a run-time error should be raised.
