You're close - the missing part is that you want to use the sum() 
function, ie:

<short-desc>{
   sum(
     for $shrtdesc in $ltnfiles//subtopic[@id = 'DEF']//short-definition
     return string-length($shrtdesc/p/text)
   )
}</short-desc>

An alternative would be to use string-join(). First join all the strings and then calculate the length:
{string-length(string-join($ltnfiles//subtopic[@id = 'DEF']/short-definition/p/text), '')}

All the best

PS: A great resource for xquery functions is http://www.xqueryfunctions.com/ 
You will find lots of stuff there ...

I think this error depends on the context of the two expressions you've 
given below - which in and of themselves look fine.

In an expression context, you need a comma between two direct element 
constructors:

<a/>, <b/>

When directly inside another direct element constructor, no comma is 
necessary (because the syntax is emulating XML itself):

<root><a/><b/></root>

When you use curly braces inside a direct element constructor, you 
return to an expression context, so commas are necessary again:

<root>{ <a/>, <b/> }</root>

You can mix the two styles:

<root>{ <a/>, <b/> }<c/><d/></root>

if you mean curly braces, they are just a way of when to engage xquery
processing

here is a simple example, if your entire query was

<test>1 + 1</test>

then when you process this it would emit exactly the same thing e.g.

<test>1 + 1</test>

but if you did

<test>{1 + 1}</test>

then the stuff in the braces would get evaluated by xquery processor
e.g. the output would look like

<test>2</test>

keep on asking questions ...

Generally, XQuery is better than XSLT for extracting specific 
information out of an XML document, and XSLT is better at making small 
changes to a document while leaving most of the content unchanged. Or to 
put it another way, XQuery is better at query and XSLT is better at 
transformation. (XQuery Update is an alternative, though, if available).

Subject: [xquery-talk] [xml-dev] XQuery 3.0 implementations vs the
	XQuery 3.0 Test Suite

Jim,

I expect Zorba to report results by the end of the year, hopefully 100%. We implement all the features,
including the optional ones.

Therefore, as documents are transitioned to Candidate Recommendation, a Call for Implementations is issued.  Implementations respond to that call by submitting their results from running the test suite and by reporting bugs they've discovered as a result.

At this point, we honestly cannot predict whether implementors will require two weeks, two months, or two quarters before they're able to submit results.

You've got a "cartesian cross product" in your for expression.... is
that really what you want?

Covert both items to lower-case() before comparing, or use your xquery
vendors custom extensions.

Use order by - if if the quote contains round brackets return 1 else
return 0, then sort by number descending.
