I'm not able to properly render an SVG tag, because it is not possible to include the xmlns:xlink="http://www.w3.org/1999/xlink" attribute. The library complains that this is not a valid attribute name.

Are you trying to render svg root element or something else? svg {} should set the namespace properly.

If you are using the 'use' element inside the svg, you have to specify the xlink namespace.

<svg width="100%" height="100%" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
  <defs>
    <g id="Port">
      <circle style="fill:inherit" r="10"/>
    </g>
  </defs>

  <text y="15">black</text>
  <use x="50" y="10" xlink:href="#Port" />
 </svg>

But I am not able to do this out of the box. Obviously, in the long run, there is likely a lot more to do to fully enable SVG support in this library (and I may end up submitting a pull for some of this functionality), but for now, allowing for the addition of this custom namespace is required.

I have a similar requirements. But in the root html tag.

<html t:type="Layout" title="Bot Crow"
     xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd" 
     xmlns:p="tapestry:parameter">
</html>

need a custom namespace for xmlns:t and xmlns:p

I tried putting it as an attribute, but it gets rejected.

        attributes["xmlns:t"] = "http://tapestry.apache.org/schema/tapestry_5_4.xsd"
        attributes["xmlns:p"] = "tapestry:parameter"

Okay for now i'm using a workaround by using String.replace to replace the xmlns to xmlns:t.

I had a similar problem and needed to define two SVG graphics：

<svg xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" xmlns="http://www.w3.org/2000/svg" height="0" width="0" style="position: absolute;">
    <defs>
        <g id="folder" fill="none">
            <path d="M285.22 37.55h-142.6L110.9 0H31.7C14.25 0 0 16.9 0 37.55v75.1h316.92V75.1c0-20.65-14.26-37.55-31.7-37.55z" fill="#FFA000"></path>

Got the same problem. I want to create epub files which require two namespaces in the header:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ops="http://www.idpf.org/2007/ops" xml:lang="de">

Trying to set either ´xmlns:ops´ or ´xml:lang´ via the attributes map results in an error ´Tag html has invalid attribute name´.

Any way to set these two entries via the DSL?

@henningBunk use raw()

const val SVG = """
<svg xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" height="0" width="0" style="position: absolute;">
    <defs>
.........
    </defs>
</svg>
"""

body {
    unsafe { raw(SVG) }
}

@XhstormR I don't get how this should work though since I will wrap my hardcoded string which represents the root element inside of the body which breaks the hierarchy. It should be the other way around. What am I missing?

Also I would have to write a lot of the html/xml myself that way, which isnt the point of a DSL.

I settled for a replacement method, but still wished it would be possible with the native DSL.

buildString {
    appendLine("""<?xml version="1.0" encoding="UTF-8"?>""")
    appendLine("""<!DOCTYPE html>""")
    appendHTML().html(
        namespace = "http://www.w3.org/1999/xhtml"
    ) {
        attributes["placeholder"] = "replace"
        ...
    }
}.replace(
    """placeholder="replace"""".toRegex(),
    """xmlns:ops="http://www.idpf.org/2007/ops" xml:lang="de""""
)
