As a result the difference in context rule becomes *ineffective*. We believe that this reflects a common misunderstanding about how "partitions" work in a label in the evaluation of context rules.<o:p></o:p></p><p>In a label .... 0D41 0D4D 0D30 .... the partition .... {0D41} {0D4D} {0D30} .... would lead to a <b><i>valid </i></b>label (given that there is no context rule for 0D30). Therefore, the alternate partition .... {0D41} {0D4D 0D30} ...., even though it generates an invalid label, is <i>ignored</i>. It does not somehow "veto" or "override" the other legal partition.<o:p></o:p></p><p>If it is somehow important to prevent Halant+Ra from following vowel sign U, then the context rule for Halant could be changed to<o:p></o:p></p><p> follows-only-C-or-0D41-and-precedes-anything-but-0D30<o:p></o:p></p><p>That would force any combination of 0D4D 0D30 to use the defined sequence and its context rule. Writing such a rule requires expressing the equivalent of [^\u0D30] in Regex notation. The formulation would be a bit involved, but not too much. <o:p></o:p></p><p class=MsoNormal>We further note that the sequence occurs one more time in the LGR for the following definition: <o:p></o:p></p><p> R → Re-Ordering Matra <br> R = (<span lang=ML style='font-family:"Kartika",serif'> െ</span>,<span lang=ML style='font-family:"Kartika",serif'> േ</span>, <span lang=ML style='font-family:"Kartika",serif'>ൈ</span>,<span lang=ML style='font-family:"Kartika",serif'> ൊ</span>,<span lang=ML style='font-family:"Kartika",serif'> ോ</span>, <span lang=ML style='font-family:"Kartika",serif'>്</span> + <span lang=ML style='font-family:"Kartika",serif'>ര)</span><br> U+0D46 (<span lang=ML style='font-family:"Kartika",serif'>െ) </span>U+0D47 (<span lang=ML style='font-family:"Kartika",serif'>േ)</span>U+0D48 (<span lang=ML style='font-family:"Kartika",serif'>ൈ) </span>U+0D4A (<span lang=ML style='font-family:"Kartika",serif'>ൊ) </span>U+0D4B (<span lang=ML style='font-family:"Kartika",serif'>ോ) </span>and <span style='color:red'>[U+0D4D (</span><span lang=ML style='font-family:"Kartika",serif;color:red'>്) </span><span style='color:red'>U+0D30 (</span><span lang=ML style='font-family:"Kartika",serif;color:red'>ര)]</span><o:p></o:p></p><p>It is not possible for a context rule to directly affect such a definition.

Even though it is the case that following 0D41 (or probably any non-consonant) this sequence does not act like a reordrant matra, the definition is never invoked in these cases, therefore, it would not be necessary to give this sequence a restricted context for the purpose of defining R. <o:p></o:p></p><p>Finally, it is not a requirement that a sequence cited in the body of a rule must be listed as a sequence in the repertoire. The latter is only necessary if the sequence is to participate in context rule evaluation (that is, if the sequence can take the place of an "anchor" in a rule).
