It would be good to be able to link to the definition of a system property.

This may be an enhancement to the @see or {@link} mechanism.

An obvious/basic suggestion is   @see property:<name>

However, simple use of "name" would require a pass over all the doc comments to determine the location (defining type, and hence page) for every property. A secondary suggestion would be to require the reference to include the defining type, as in   @see property:<type>#<name>
