The links to the licence texts are definitely incorrect : Wikipedia
articles are not a valid source for the texts of these licences, and
you also need to point directly to a versioned text of these licences,
or even better link to a legal copy of these copyrighted texts
directly on your site (hosted on the same domain to assert that it is
owned and managed in the same realm as your document page). Without
this change, there is still no legal term, and the licence grant is
weak (mostly inexistant).
Note that even Wikipedia and Wikimedia Commons take a lot of care of
identifying the licences applicable to their contents very precisely
(this is a requirement for users of these sites) and point to their
text exactly.
Also the term "dual-licenced" is commonly used in the vernacular
language, but legally, it may be confusive (do others have to apply
both simultaneously?). It should better be a sentence like:
This document is licenced to you at no charge, under any of the
following licences, at your convenience :
* CC-BY-CA : Creative Commons licence (with authors attribution
required, share-alike), version x.x (or later)
* LGPL : GNU Lesser General Public Licence, version x.x (or later)
For the LGPL, you should also include the warranty disclaimer sentence
sugested after the end of the legals terms of the LGPL, unless you
want to assume at least all the legal warranties yourself or
propose/sell such service. Read the two licence sites for details on
how to apply these licences to your contents. Note that the LGPL
allows implementers to include it in their implementation and provide
it only in its binary form without having to provide the source of the
rest of their application in which the licenced material is used. If
you want to be even more lieberal about source code availability to
further licensees you may also choose a BSD licence as well (the BSD
licence is compatible with all open and/or free licences, the only
requirement being the copyright notice with author's attribution).
Please look at the respective GNU.org and CreativeCommons.org sites to
find the exact licence version that meets your requirements, and
specify the versions number explicitly on your page (if you accept
later versions specify it as well with "or later version"). For
example I suggest LGPL v3.0 or later (but you may want v2.1 or even
v2.0 as the minimum licence)
