## Macro Definition Documentation

## SVN_PROP_REVISION_PREFIX

#define SVN_PROP_REVISION_PREFIX SVN_PROP_PREFIX "revision-"

The prefix reserved for copies of (ephemeral) transaction properties designed to outlive the transaction.

Administrators may choose to, in their pre-commit hook scripts, copy the values of one or more properties named `SVN_PROP_TXN_PREFIX` + "something" to new properties named `SVN_PROP_REVISION_PREFIX` + "something", allowing that information to survive the commit-time removal of ephemeral transaction properties.

## SVN_PROP_TXN_CLIENT_COMPAT_VERSION

#define SVN_PROP_TXN_CLIENT_COMPAT_VERSION SVN_PROP_TXN_PREFIX "client-compat-version"

Identifies the client version compatibility level.

For clients compiled against Subversion libraries, this is `SVN_VER_NUMBER`. Third-party implementations are advised to use similar formatting for values of this property.
