xquery '//book/title' library.xml
# Count elements
xquery 'count(//item)' catalog.xml
# Read from a query file
xquery -f transform.xq input.xml
# Query a directory of XML files
xquery 'collection()//product[price > 50]' ./data/
# JSON output
xquery -o json 'map { "count": count(//item) }' data.xml
# Read from stdin
cat data.xml | xquery '//item/@name'
# Show execution plan
xquery --plan 'for $x in 1 to 10 return $x * $x'
# Show timing breakdown
xquery --timing '//item' large-catalog.xml

Takes **PhoenixmlDb.Core 2.0.0** (unchanged — Core runs its own cadence).
### Added
**The built-in list types are now cast and castable targets** (#74). XQuery 3.0 permits
`xs:IDREFS`, `xs:NMTOKENS` and `xs:ENTITIES` in this position even though a list type is not an
item type: the lexical form is split on whitespace and each token cast to the member type, so the
result is a **sequence**.
```xquery
"a b c" cast as xs:IDREFS (: ('a','b','c'), of type xs:IDREF* :)
"a b c" castable as xs:IDREFS (: true :)
"1 2 3" castable as xs:IDREFS (: false :)
```
These previously reported `XPST0051: 'xs:IDREFS' is not a recognized atomic type` — a true
statement about a list type and the wrong answer in this position.
### Fixed
**The `xquery` CLI printed a .NET type name for a function item** (#76, closes #75).
```
$ echo 'function($x){$x}' > q.xq && xquery -f q.xq
PhoenixmlDb.XQuery.Execution.InlineFunctionItem
```
`PhoenixmlDb.XQuery.Cli` carries its own `ResultSerializer` alongside the engine's
`XQueryResultSerializer`, and it had no case for a function item at all, so one fell through to
`item.ToString()`.
### Conformance
**W3C QT3 29,803 / 31,379 (94.98%)**, up 63 from 2.1.0's 29,740.
Worth stating how those 63 were earned, because not every conformance movement is the same kind:
**#74 implements the feature**, so the denominator stays 31,379 and the passes rise. That is
different from a harness-honesty fix, which raises the percentage by removing cases from the
count. Both are legitimate; only one of them means the engine does more than it did.
