[basex-talk] Variable value

Hi, I have stambled upon an unexpected issue concerning the value of a variable (in BaseX 10.6), which seems to be affected by an independent function. I have a function like page:open-url($an1) which takes a url as a parameter and opens a document. The url usually consists of an invariable p

[basex-talk] Java 11

Hi All, On the BaseX website (https://basex.org/download/ ), it is specified that “Java 11 is required to install and run BaseX (10.1)” . Since it is not specified “Java 11 or higher”, I am wondering whether this requirement is actually meant to be strict. Thanks!

Hi When maps are serialized, the text nodes of an element (e.g., r/text()) are serialized without quotes and tests with "instance-of" show that they actually are text nodes: Couldn't they be serialized with quotes? I see that with data(), the text is serialized with quotes although it is xs:u
