11092	Boost write_graphml writes non-conformant GraphML for boolean attributes	freedesktop@…	Jeremiah Willcock	"Boolean attributes are serialized as 0 and 1. They should be written as ""false"" and ""true"" instead.

The GraphML spec does not specify what values are acceptable, but according to the GraphML primer, ""The type of the GraphML-Attribute can be either boolean, int, long, float, double, or string. These types are defined like the corresponding types in the Java(TM)-Programming language."".

In source code, Java would allow only ""true"" and ""false"" for boolean values. If we add any representation that Java's Boolean.parseString() recognizes, the case wouldn't matter, but ""1"" still wouldn't parse as true.

Other libraries like NetworkX fail to parse GraphML with boolean attributes written by Boost. See also https :// github.com / networkx / networkx / pull / 1063."	Bugs	new	To Be Determined	graph	Boost 1.54.0	Problem
