Review comment:
I can see the need for a new test file as you are adding a new feature
here and I don't really think we should change the existing GraphML files. As a
suggestion, it would be nice if the new test file simply was a modification of
the existing "modern" data set. We try to keep the datasets consistent when we
can even for test. It's not always possible but in this case I think it would
be easy to copy the tinkerpop-modern.xml file and modify it to include default
values. An easy one would be to include defaults for "lang" and/or "age" which
aren't shared across all vertex labels. For edge defaults I suppose you would
have to fabricate something as all edges have "weight" but at least the base
graph data would be the same. if you have some good reason for sticking with
this data as you have though, please let me know, otherwise it would be nice to
see our more familiar dataset in use here.

> Support default attribute values in GraphMLReader
> -------------------------------------------------
>
> Key: TINKERPOP-848
> URL: https://issues.apache.org/jira/browse/TINKERPOP-848
> Project: TinkerPop
> Issue Type: Improvement
> Components: io
> Affects Versions: 3.0.2-incubating
> Reporter: Pavel Klinov
> Priority: Trivial
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> Looking at the code of GraphMLReader I see that it doesn't support default
> values of attributes, which are allowed by the GraphML spec. This is a bit
> annoying especially if the input defines default values for attributes which
> are used for mandatory data, e.g. edge labels.
> One small example is the sample graph at [1]. "d_e" is the label attribute
> with a default value. There're <edge .. /> elements w/o body later in the
> document and reading those will throw a "java.lang.IllegalArgumentException:
> Label can not be null" exception (if the vendor considers edge labels
> mandatory).
> I'd personaly squash both keyIdMap and keyTypesMap into a single String ->
> AttrInfo map, where AttrInfo would contain information about the data
> attribute name, type, and the default value.
