Description

We need to make sure that whatever syntax we have for cross referencing continues to work even as we look at adding more sources of configuration data.

examples: sysprops, late binding information from the registry to link to other components.

We may need to do something more typed, eg

{attr:property}

or even maybe

{@property}

,

{@/global/property}

to indicate attributes. And maybe even cross reference internal/resources

size:"

{@//resources/components/regions/yarn.component.instances}

"

Other references we could do with another syntax in the {}. Example

{env:Path}

,

{sysprop:java.home}

We'll need to allow for the { to be escaped somehow.
