+/** Parse UNO URLs into their components.
+
+    The ABNF for UNO URLs is as follows (see RFCs 2234, 2396, also see
+    <http://udk.openoffice.org/common/man/spec/uno-url.html>):
+
+    uno-url = "UNO:" connection ";" protocol ";" object-name
+    connection = descriptor
+    protocol = descriptor
+    descriptor = name *("," parameter)
+    name = 1*alphanum
+    parameter = key "=" value
+    key = 1*alphanum
+    value = *vchar
+    valchar = unreserved / escaped / "$" / "&" / "+" / "/" / ":" / "?" / "@"
+    object-name = 1*ochar
+    ochar = unreserved / "$" / "&" / "+" / "," / "/" / ":" / "=" / "?" / "@"
+
+    Within a descriptor, the name and the keys are case insensitive, and within
+    the parameter list all keys must be distinct.
+
+    Parameter values are encoded using UTF-8.  Note that parsing of parameter
+    values as done by UnoUrl and UnoUrlDescriptor is not strict:  Invalid UTF-16
+    entities in the input, as well as broken escape sequences ("%" not followed
+    by two hex digits) are copied verbatim to the output, invalid bytes in the
+    converted UTF-8 data are considered individual Unicode characters, and
+    invalid UTF-16 entities in the resulting output (e.g., a high surrogate not
+    followed by a low surrogate) are not detected.
