Template:EquationRef

The pair of templates {{Template:EquationRef}} and {{Template:EquationNote}} is used for labeling equations in text.

For example, {{EquationRef|Eq. 1}}: <math>x^2+x+1=0</math> results in:

Eq. 1

$x^2+x+1=0$

Here, the identifier "Eq. 1" is a label which can be later referred to with a call to {{Template:EquationNote}}. That is, {{EquationNote|Eq. 1}} produces a link Eq. 1 to this equation.

Similarly, {{EquationRef|2|Eq. 2:}} <math>x^2-2x+1=0</math> results in:

Eq. 2:

$x^2-2x+1=0$

which can be referred to by {{EquationNote|2}} (i.e., 2 ) or even {{EquationNote|2|Equation 2}} (i.e., Equation 2 ).

This is a very static version of equation numbering. I've tried to us the <ref> tags, but until now without success:

$x^2+x+1=0$ [Eq. 1]

$x^2-2x+1=0$ [Eq. 2]

$x^2-2x+1=0$

$x^2-2x+1=0$ Eq. 4

This has two drawbacks, first one has to number the cite tags by hand "-0","-1", "-2" and second one needs the <references group="Eq. "/> at the bottom of the page. If anybody has a new idea, please let me now.
