Only comes with experience.  My assumption was that if I see a start tag 
where the first part has a colon in it, that is referring to XML namespaces:

<http://www.w3.org/TR/REC-xml-names/>

Correction: "HTA:APPLICATION" might have worked as well.  Because MSXML does 
not appear to be *fully* namespace-aware.  I found that out when writing 
JSX:xpath.js and I had to trim the namespace prefix for the XPath expression 
with *user-defined* prefixes to work in Internet Explorer:

<http://PointedEars.de/websvn/filedetails.php?repname=JSX&path=/trunk/xpath.js>

(No line numbers yet; look for `else if (isMethod(contextNode, 
"selectNodes"))'.)

ACK.

I googled "HTA", which after a few not so useful links to "*H*ochschule 
Luzern - *T*echnik & *A*rchitektur" lead me to the German Wikipedia article 
[1], in which was a link to the MSDN Library as the first one in the section 
"Weblinks" [2].  Then as I saw that despite the German-language interface 
the referred content was in English, so I tried "en-us" instead of "de-de".  
This worked.  Then I clicked on "border", and there it is.
