> at least reachable by API via Gremlin console for GraphML serialization
It's reachable - just configured the `GraphWriter`
[directly](http://tinkerpop.apache.org/docs/current/reference/#_graphml_reader_writer)
rather than rely on the default provided by `graph.io(graphml())`
```java
final Graph graph = TinkerFactory.createModern();
try (final OutputStream os = new FileOutputStream("tinkerpop-modern.xml")) {
graph.io(IoCore.graphml()).writer().normalize(true).create().writeGraph(os,
graph);
}
```

i think #891 should definitely go in as there is not much to think about on
that one. this one is fine, but the sorting should make sense for the full
scope of identifiers from all different graphs. It can't be optimized to work
for just TinkerGraph defaulted to `Integer` values - it wouldn't be fair to
other graphs if we had that kind of favoritism :smile: I can think about the
sorting some more, but right now i'm not sure what would be best.
