Wow, this is what I've been waiting for! I was just thinking the other 
day that XSLT is cool and all, but it clearly does not have enough Greek 
symbols. I can't believe how perfectly your proposal addresses my 
deepest needs as a human being!



Thank you Sean, I am indebted to you.

I have chosen well-known Greek letters and various printers' symbols 
for the operators.



The following table illustrates and specifies this formalism:



    N1 apply-imports
    N2 apply-templates
    O attribute
    N attribute-set
    N; call-template
    N> choose
    O comment
    N< copy
    N3 copy-of
    N decimal-format
    O element
    N8 fallback
    N6 for-each
    O if
    N) import
    N include
    N key
    N< message
    N namespace-alias
    N= number
    O otherwise
    N output
    N' param
    N preserve-space
    N5 sort
    N? strip-space
    N# stylesheet
    N template
    N9 text
    N$ transform
    N: value-of
    N4 variable
    O when
    O with-param
    N  processing-instruction

    B?... test="..."
    b... name="..."
    b	... match="..."
    B'... select="..."
    B+...B; (general attribute value)

The preceding explanation aside, the best way to appreciate MatTS is 
by simply trying it out -- MatTS as a visualization application is 
itself implemented in browser-accessible XSLT, and so can be used to 
view other XSLTs as well as itself:

Compare with the clutter of those XSLs when viewed in conventional 
XSLT notation:
