XML Language help

Hello,

I am extending the XML language you provide. Right now what I am trying to do is make certain tags, based on the tag name, be in a particular state. Is this the best way to do it? 
  
<State Key="MyStartTagState" Token="MyStartTagDefaultToken" Style="MyTagNameStyle">
   <!-- Scopes -->
   <Scopes>
       <Scope>
           <ExplicitPatternGroup Type="StartScope" Token="MyStartTagStartToken" Style="MyTagDelimiterStyle" PatternValue="<" 
              LookAhead="my:tag1|my:tag2|my:tag3" />
           <RegexPatternGroup Type="EndScope" Token="MyStartTagEndToken" Style="MyTagDelimiterStyle" PatternValue="/? >" />    
       </Scope>
   </Scopes>

   <!-- Patterns Groups -->
   <PatternGroups>
       <RegexPatternGroup Token="MyStartTagNameToken" Style="MyTagNameStyle" LookAhead="{NonWordMacro}" PatternValue="{TagNameMacro}+" />
   </PatternGroups>

   <!-- Child States -->
   <ChildStates>
       <ChildState Key="MyStartTagAttributeState" />
   </ChildStates>
</State>

<State Key="MyEndTagState" Token="MyEndTagDefaultToken" Style="MyTagNameStyle">
    <!-- Scopes -->
    <Scopes>
        <Scope>
            <ExplicitPatternGroup Type="StartScope" Token="MyEndTagStartToken" Style="MyTagDelimiterStyle" PatternValue="</" 
                LookAhead="my:tag1|my:tag2|my:tag3" " />
            <ExplicitPatternGroup Type="EndScope" Token="MyEndTagEndToken" Style="MyTagDelimiterStyle" PatternValue=">" />    
        </Scope>
    </Scopes>
    <!-- Patterns Groups -->
    <PatternGroups>
        <RegexPatternGroup Token="MyEndTagDefaultToken" PatternValue="[^>]+" />
    </PatternGroups>
</State>

Small update, i changed it to: 
  
   LookAhead="my: (tag1 | tag2 | tag3) {NonTagNameMacro}"
Is there a better way to do this than a potentially gigantic LookAhead list?

Right now there isn't a better way to do it unless you use a semantic parser PostProcess phase and reassign CustomHighlightingStyles depending on the token's text. But that won't alter the state. We're open to all suggestions if you have any though.
