Attributes with quotes within entities

[Soren Kuula]

Hi,

I'm writing some DocBook with lots of math formulae. For every mathematical expression in my document, I have to enclose it in :

<math xmlns="http://www.w3.org/1998/Math/MathML"> blah </math>

so I thought of declaring entities in the DTD extension so I can just use

&mathbegin;
blah
&mathend

Problem is, how do I declare there ?

<!ENTITY mathbegin <math xmlns="http://www.w3.org/1998/Math/MathML">>

<!ENTITY mathbegin '<math xmlns="http://www.w3.org/1998/Math/MathML">'>

<!ENTITY mathbegin "<math xmlns='http://www.w3.org/1998/Math/MathML'>">

<!ENTITY mathbegin "<math xmlns="http://www.w3.org/1998/Math/MathML">">

<!ENTITY mathbegin "<math
xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot;>">

all don't work (with Xalan). The problem seems to be the quotes in the text I want to declare an entity for ...

Surely there must be a solution ...

&mathbegin;
blah
&mathend

Sorry, you can't do that: elements must start and end in the same entity.

But you can shorten it:

<math xmlns="http://www.w3.org/1998/Math/MathML"> blah </math>

Declare a fixed attribute for the <math> element:

<!ATTLIST math xmlns CDATA #FIXED "http://www.w3.org/1998/Math/MathML">

and then you can just use

<math>
blah
</math>
