<h2><a id="parsing.wellformed"></a>A.1 Use of MathML as Well-Formed
XML</h2>
<p>A MathML document must be a well-formed XML document using elements in the MathML
namespace as defined by this specification, however it is not required that the document
refer to any specific Document Type Definition (DTD) or schema that specifies MathML.
It
is sometimes advantageous <em>not</em> to specify such a language definition as these
files are large, often much larger than the MathML expression and unless they have
been
previously cached by the MathML application, the time taken to fetch the DTD or schema
may
have an appreciable effect on the processing of the MathML document.</p>
<p>Note that if no DTD is specified with a DOCTYPE declaration, that entity
references (for example to refer to MathML characters by name) may not be used. The
document should be encoded in an encoding (for example UTF-8) in which all needed
characters may be encoded as character data, or characters may be referenced using
numeric
character references, for example &#x222B; rather than &int;</p>
<p>If a MathML fragment is parsed without a DTD, in other words as a well-formed XML
fragment, it is the responsibility of the processing application to treat the white
space
characters occurring outside of token elements as not significant.</p>
<p>However, in many circumstances, especially while producing or editing MathML, it is
useful to use a language definition to constrain the editing process or to check the
correctness of generated files. The following section, <a href="#parsing.usingrnc">Section A.2 Using the RelaxNG Schema for MathML3</a>,
discusses the RelaxNG Schema for MathML3 <a href="appendixg.html#RELAX-NG">[RELAX-NG]</a>, which forms a normative
part of the specification. Following that, <a href="#parsing.usingxsd">Section A.4 Using the MathML XML Schema</a>, and <a href="#parsing.usingdtd">Section A.3 Using the MathML DTD</a> discuss alternative languages definition using the document type
definitions (DTD) and the W3C XML schema language, <a href="appendixh.html#XMLSchemas">[XMLSchemas]</a>, both of
which are derived from the normative RelaxNG schema automatically. One should note
that
the schema definitions of the language is currently stricter than the DTD version.
That
is, a schema validating processor will declare invalid documents that are declared
valid
by a (DTD) validating XML parser. This is partly due to the fact that the XML schema
language may express additional constraints not expressable in the DTD, and partly
due to
the fact that for reasons of compatibility with earlier releases, the DTD is intentionally
forgiving in some places and does not enforce constraints that are specified in the
text
of this specification.</p>
</div>
<div class="div2">
<h2><a id="parsing.usingrnc"></a>A.2 Using the RelaxNG Schema for MathML3</h2>
<p>MathML documents should be validated using the RelaxNG Schema for MathML, either in
the XML encoding (<a href="http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rng">http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rng</a>)
or in compact notation (<a href="http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rnc">http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rnc</a>)
which is also shown below.</p>
<p>In contrast to DTDs there is no in-document method to associate a RelaxNG schema with
a document.</p>
<p>We provide five RelaxNG schema for MathML3 in five parts:
</p>
<ul>
<li>
<p>The grammar for full MathML</p>
</li>
<li>
<p>The grammar for elements common to Content and Presentation</p>
</li>
<li>
<p>The grammar for Presentation MathML</p>
</li>
<li>
<p>The grammar for Strict Content MathML</p>
</li>
<li>
<p>The grammar for Content MathML3</p>
</li>
</ul>
<div class="div3">
<h3><a id="parsing.rnc.full"></a>A.2.1 Full MathML</h3>
<p>The RelaxNG schema for full MathML builds on the schema describing the various parts
of the language which are given in the following sections. It can be found at <a href="http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rnc">http://www.w3.org/Math/RelaxNG/mathml3/mathml3.rnc</a>.</p>
