           Summary: [FO11]
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Functions and Operators 1.1
        AssignedTo: mike@saxonica.com

fn:parse  says ...

This function takes as input an XML document represented as a string,
...The precise process used to construct the XDM instance is
implementation-defined. In particular, it is implementation-defined whether DTD
validation is invoked, and it is implementation-defined whether an XML 1.0 or
XML 1.1 parser is used.

I assume that it would be conformant to supply the xpath engine with a parser
that accepted some other syntax than xml and returned an XDM tree (or
equivalently returned the sax events to allow you to build an XDM tree).
HTML5 being a topical example. Practically speaking, if an html5 parser
exposing sax events is used the system probably can't tell anyway. Accepting
html is arguably allowed by the "implementation defined" quoted above except
that the error condition

A dynamic error [err:FODC0006] is raised if the content of $arg is not a
well-formed and namespace-well-formed XML document.

has to be read with care if it is not to be interpreted as saying a system must
raise an error if presented with HTML markup. Presumably (that is, I presume,
but I'm unsure if I should presume) the intention is that FODC0008 is raised if
an XDM tree can not be constructed by the "implementation defined process" when
supplied the string $arg.
