Schema
You can think of the JSON as Directed Graph source code and the XML as compiled code. The XML must conform to the schema at https://gerrit.onap.org/r/gitweb?p=ccsdk/sli/core.git;a=blob;f=sli/common/src/main/resources/svclogic.xsd;hb=refs/heads/master. The XML schema reveals what nodes are supported and which attributes are appropriate for each node. This page explains each node in plain English with accompanying code snippets as an alternative to reading the schema file itself.
