Need a small hint for custom .xshd :)

So hi all :)

First i have to say this is a great Control, saved me so much time! But currently i have a small problem with a custom xshd.
I still use the ics.Texteditor, sadly i cant switch to Avalon :/ Hope you can still manage to help me in this one. 

Syntax that i have to highlight:

[XYZ]
   <string>name:value
   <integer>name:value 
[/XYZ]

My needs:

[XYZ][/XYZ] <- Any Color (done)
<string> <- Any Color (done)
name <- Any Color (done)
: <- Any Color (buggy is same color as value)
value <- Any Color (buggy is same color as ':' )

I got everything nice and fine so far, my only problem is i cant color the values without coloring ':' to :<

My current xshd:

<?xml version="1.0"?>

<SyntaxDefinition name = "custom" extensions = ".txt">

<RuleSets>

<RuleSet ignorecase="true">

<Delimiters></Delimiters>

<Span name = "comments" bold="false" italic="false" color="#a8a8a8" stopateol="true">

<Begin>//</Begin>

</Span>

<Span name = "top" bold="false" italic="false" color="#54afe8" stopateol="true">

<Begin>[</Begin>

<End>]</End>

</Span>

<Span name = "type" bold="false" italic="false" color="#f24544" stopateol="true">

<Begin>&lt;</Begin>

<End>&gt;</End>

</Span>

<Span name = "values" rule="insideValues" bold="false" italic="false" color="#3d8236" stopateol="true">

<Begin>:</Begin>

</Span>

</RuleSet>

<RuleSet name="insideValues" ignorecase="true">

 <Delimiters></Delimiters>

<KeyWords name = "deli" bold="false" italic="false" color="Black">

<Key word = ":" />

</KeyWords>

</RuleSet>

</RuleSets>

</SyntaxDefinition>
