after a few weeks of distance, i returned to the subject with fresh eyes...

With ReStructuredText, you try to capture the indent level in this part: 
(...)
	<RegExpr attribute="Code" String="::$" context="CodeBlock" />
(...)

<context name="CodeBlock" attribute="Code" lineEndContext="#stay">
	<RegExpr attribute="Code" String="^\s" context="Code" />
</context>

<context name="Code" attribute="Code" lineEndContext="#stay">
	<RegExpr attribute="Normal" String="^\S" lookAhead="true" 
context="#pop#pop" />
</context>

but it seems just equal to the last regex -> changing context when a 
line doesn't start with some kind of white space, and this is doing the same 
result for me:

<RegExpr attribute="Code" String="::$" context="Code" />
</context>

<context name="Code" attribute="Code" lineEndContext="#stay">
	<RegExpr attribute="Normal" String="^\S" lookAhead="true" context="#pop" 
/>
</context>

the test case:

(with :  RegExpr attribute="Code" String="script."...)

html
    body
        #head.center
            h1 test
      
            script.
                console.log('test');
                var i = 6;
                for (i; i>1; i--) {
                   console.log(i);
               }
        
      div			<==== context not switch
	p blabla

so, i returned to the dynamic rules and to the capture regex idea, and or i 
discovered a bug, or i missed something. If i do that: 

<RegExpr attribute="Code" String="sc(ri)pt." context="Code"  dynamic="true" />

i should capture "ri", and i should use it like that in according to the 
manual

<context name="Code" attribute="Code" lineEndContext="#stay">
	<RegExpr attribute="Normal" String="^%1" context="#pop" 
/>

html
    body
        #head.center
            h1 test
      
            script.
                console.log('test');
                var i = 6;
                for (i; i>1; i--) {
                   console.log(i);
               }
ri                         <==== should be detected?! but it is not!
      div			
	p blabbla


what I didn't understand?

thx
