Modified: src/main/org/jboss/mx/metadata XMLMetaData.java
Added: src/main/org/jboss/mx/metadata JBossXMBean10.java
XMBeanMetaData.java
Log:
separate parsing of different DTDs (so we can keep supporting older schemas
as new develop). Builder class is picked based on SYSTEM or PUBLIC ID,
XMLMetaData is the aggregate for all xml based builders.
