Comment (by Will Plano):

 I've just come across this defect, also while trying to parse a yEd file.

 According to the documentation at
 graphml.graphdrawing.org/specification/schema_element.xsd.htm the
 for="graphml" key attribute is for data associated with "the whole
 collection of graphs described by the content of <graphml>"
 Since read_graphml only deals with a single graph in the file, I beleive
 it is correct to silently ignore this section.

 As for how yEd uses it, it looks like it's for shared resources within the
 file...

 {{{#!xml
 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 ...
 snip schema definitions for spam filter
 ...
   <!--Created by yFiles for Java 2.10-->
   <key for="graphml" id="d0" yfiles.type="resources"/>
 ...
 snip
 ...
   <data key="d0">
     <y:Resources/>
   </data>
 </graphml>
 }}}

 see the attached patch on the duplicate ticket 7155
