Thanks for reporting the issue, and supplying the repro. I have reproduced the issue (on the Chrome browser), and added browser test iss5019.

The error gets thrown while processing the apply templates call in push mode. The focus is the window.document (as returned from ixsl:page()), but while traversing this tree, we attempt to process the html element's attributes (see Axis.attribute in DomUtils.js) but hit a problem with this xml:lang attribute. This attribute node has properties: attr.prefix = null, attr.prefix = null, attr.localName = "xml.lang", so we then get an error calling Atomic.XS.QName.fromParts, because the local name is invalid.
