<p class="MsoNormal">Dear SEA-SA colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As you will already have seen in the note I just sent to our CSS colleagues, we think we need to make some modest changes, via corrigenda, to one specific definition in the ASL and to some other uses of the term “capability”:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Sec 1.5, Pg 1-8: <o:p></o:p></u></b></p>

<p class="MsoNormal" style="margin-left:.5in">From:<o:p></o:p></p>
<p style="margin-left:.5in"><b><span style="font-size:12.0pt;font-family:"TimesNewRomanPS",serif">service</span></b><span style="font-size:12.0pt;font-family:"TimesNewRomanPSMT",serif">: (RASDS) A set of capabilities that a component provides to another component
via an interface. A service is defined in terms of the set of operations that can be invoked and performed through the service interface. Service specifications define the capabilities, behavior, and external interfaces, but do not define the implementation.
(Reference [17].) </span><o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">To:<o:p></o:p></p>
<p style="margin-left:.5in"><b><span style="font-size:12.0pt;font-family:"TimesNewRomanPS",serif">service</span></b><span style="font-size:12.0pt;font-family:"TimesNewRomanPSMT",serif">: (RASDS) A
</span><b><span style="font-size:12.0pt;font-family:"TimesNewRomanPS",serif">service

<p style="margin-left:.5in">Rationale: the quoted definition is from MO, M&C Services, and not from RASDS. Furthermore, it is inaccurate since is somewhat casually inverts the relationship between “service” and “capability”. A more accurate rendering of
the MO definition would be:<o:p></o:p></p>
<p style="margin-left:.5in"><b><span style="font-size:12.0pt;font-family:"TimesNewRomanPS",serif">service</span></b><span style="font-size:12.0pt;font-family:"TimesNewRomanPSMT",serif">: (<span style="color:red">MO M&C Services</span>) A set of

<p style="margin-left:.5in">Rationale:<o:p></o:p></p>
<p style="margin-left:.5in">The items in the list that follow this are all titled as “Services”.<o:p></o:p></p>
<p>There are other uses of the word “capability” in the ASL document that are sufficiently broad in nature as to not require changes, but I believe that these specific, modest, changes are essential for clarity and consistency.<o:p></o:p></p>
<p>Does anyone object to making these changes via corrigenda? And if so, please clearly state your rationale.<o:p></o:p></p>
