+Validates that a value is a valid semantic version string according to the
+`Semantic Versioning`_ specification. This constraint supports various
+version formats including partial versions, pre-release versions, and
+build metadata.

+Options
+-------
+
+``strict``
+~~~~~~~~~~
+
+**type**: ``boolean`` **default**: ``true``
+
+When set to ``true``, the version must strictly follow the official
+`Semantic Versioning`_ specification. This means:
+
+- No "v" prefix is allowed (use "1.2.3", not "v1.2.3")
+- A full version is required (major.minor.patch)
+
+When set to ``false``, common version variations are allowed:
+
+- The "v" prefix is accepted (e.g., "v1.2.3")
+- Partial versions are valid (e.g., "1", "1.2")

+Valid Version Examples
+----------------------
+
+When using ``strict: true`` (default), the following are valid:
+
+- ``1.2.3`` (full version)
+- ``1.2.3-alpha`` (pre-release)
+- ``1.2.3-beta.1`` (pre-release with numeric identifier)
+- ``1.2.3+20130313144700`` (with build metadata)
+- ``1.2.3-beta+exp.sha.5114f85`` (pre-release and build metadata)
+
+When using ``strict: false``, additional formats are accepted:
+
+- ``1`` (partial version)
+- ``1.2`` (partial version)
+- ``v1.2.3`` (with "v" prefix)
+- ``v1.2.3-alpha`` (prefix with pre-release)
