我有一组 XQuery 转换，我正在对存储在 Sedna 数据库中的文件运行这些转换。它们都具有大致以下格式：
declare namespace ns0 = "http://www.someuri.com/foo.xsd";
declare namespace ns1 = "http://www.someuri.com/bar.xsd";
(:Declare a few functions like the following:)
declare function local:to-xs-boolean(
$string as xs:string?
)
as xs:boolean? {
if (fn:upper-case($string) = 'Y') then
xs:boolean('true')
else
if (fn:upper-case($string) = 'N') then
xs:boolean('false')
(:if it isn't Y or N then attempt a normal cast - this will fail if it
it isn't any of 'true', 'false', 1, or 0 :)
else
if ($string != '') then
xs:boolean($string)
else
()
(:endif:)
(:endif:)
};
(:Omitted several other functions:)
(:Start the main program:)
(: { :)
for $formName in /ns0:formName
return
<ns1:newFormName>
{
let $address := $formName/ns0:Address
return
<NewAddress>{
(:Omitted code and elements unrelated to this question:)
}</NewAddress>
}
(:Omitted code and elements unrelated to this question:)
</ns1:newFormName>
现在这是我的问题。你看到'for'正上方的那条线，上面写着'（：{:)'？它应该是一条评论，但由于某种原因，它对我的查询的正确功能至关重要。如果我完全删除它（或从评论中删除'{'），我会得到
SEDNA Message: ERROR XPDY0002
It is a dynamic error if evaluation of an expression relies on some part of the dynamic context that has not been assigned a value.
如果我取消注释它（所以该行只是读取'{'）我得到
SEDNA Message: ERROR XPST0003
It is a static error if an expression is not a valid instance of the grammar defined in A.1 EBNF.
Details: at (393:1), syntax error, unexpected {
at (798:33), syntax error, unexpected end of file, expecting "," or }
如果我同时取消注释并在文件末尾添加匹配的“}”，我会得到
SEDNA Message: ERROR XPST0003
It is a static error if an expression is not a valid instance of the grammar defined in A.1 EBNF.
Details: at (393:1), syntax error, unexpected {
如果我在该评论中添加其他文本（如'（：text foo bar baz（）blah {:)'），只要我将'{'留在那里，它就会继续工作。
有没有人以前见过这种情况或知道可能是什么原因造成的？这并不是一个真正的关键问题（我可以确保在我的所有转换中都有'(:{:)'），但这真的让我很好奇。因此，感谢您的帮助，甚至只是让我感到困惑。
哦，另一个快速说明 - 我不知道它是否有任何区别，但我正在使用 Charles Foster 的 Sedna API (http://www.cfoster.net/sedna/) 从 Java 中运行查询
编辑：这是我刚刚写的一个不同的查询，它显示了同样的问题。这对我来说似乎可以重现，但如果它与语法错误相关，它可能只是我重现了语法错误。我也会留下旧的，所以这个问题的未来观众不会感到困惑。

如果这是一个语法错误，那么有人会向我指出它在哪一行吗？
