+ Specification (from draft-leach-uuids-guids-01.txt )
+
+ <p>
+ A UUID is an identifier that is unique across both space and time,
+ with respect to the space of all UUIDs. To be precise, the UUID
+ consists of a finite bit space. Thus, collision cannot be avoided in
+ principle. A UUID can be used for multiple purposes, from tagging objects
+ with an extremely short lifetime, to reliably identifying very persistent
+ objects across a network.
+
+ <p>
+ The generation of UUIDs does not require that a registration
+ authority be contacted for each identifier. Instead, Version 4 UUIDs are
+ generated from (pseudo unique) sequences of (pseudo) random bits.

+/** Creates named UUIDs.
+
+ <p>
+ The version 3 UUID is meant for generating UUIDs from <em>names</em> that
+ are drawn from, and unique within, some <em>name space</em>. Some examples
+ of names (and, implicitly, name spaces) might be DNS names, URLs, ISO
+ Object IDs (OIDs), reserved words in a programming language, or X.500
+ Distinguished Names (DNs); thus, the concept of name and name space
+ should be broadly construed, and not limited to textual names.
+
+ <p>
+ The requirements for such UUIDs are as follows:
+
+ <ul>
+ <li> The UUIDs generated at different times from the same name in the
+ same namespace MUST be equal
+
+ <li> The UUIDs generated from two different names in the same namespace
+ should be different (with very high probability)
+
+ <li> The UUIDs generated from the same name in two different namespaces
+ should be different with (very high probability)
+
+ <li> If two UUIDs that were generated from names are equal, then they
+ were generated from the same name in the same namespace (with very
+ high probability).
+ </ul>
+
+ @param pTargetUUID pointer to at least 16 bytes of memory. After the call
+ it contains the newly generated uuid in network byte order.
+ @param pNameSpaceUUID The namespace uuid. Below are some predefined ones,
+ but any arbitrary uuid can be used as namespace.
