<p class="MsoNormal">Dear Mailing List,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I just started developing in Isabelle/ML and I tried to consult the implementation manual but could not find an answer to my question so I will try to post it here.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a theorem which was proven in a certain local theory context (a locale in this case).<o:p></o:p></p>
<p class="MsoNormal">Now I want to use this theorem in another local theory context (an extension of the original locale).<o:p></o:p></p>
<p class="MsoNormal">However, when I try to use it for a proof in the new locale I get the following error message:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Undeclared hyps: xxx<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(Here the xxx refers to some assumptions of the original locale)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since the new locale is an extension of the original locale, I guess it should be possible to use the theorem in this new context but I could not figure out how.<o:p></o:p></p>
<p class="MsoNormal">Thus I was wondering if someone here has an idea of how I can import the theorem from the original locale to the extended one?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks a lot for your help,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
