A set of reusable XSLT components.

<a xmlns="my-ns"/>

<b xmlns="my-ns"/>

(xsl/template {:match "a"} [:b])

(xsl/template {:match "a"}
  (xsl/element {:name "b"}))

<xsl:template match="a">
  <!-- note the empty xmlns namespace declaration -->
  <b xmlns=""/>
</xsl:template>

<xsl:template match="a">
  <b/>
</xsl:template>

(xml/alias-uri 'my-ns "my-ns-uri")

(xsl/stylesheet {:version 3.0 :xmlns "my-ns-uri"}
  (xsl/template {:match "a"} [::my-ns/b]))

Write and execute XSLT transformations with Clojure.

## XML namespaces

Scenario:

- Your source XML document is in an XML namespace.
- You want to transform that document with Sigel into the same namespace.
- You want to write literal XML elements in your transformation, instead of
  using `xsl:element`.

For example, you want to transform this:

```xml
<a xmlns="my-ns"/>
```

To this:

```xml
<b xmlns="my-ns"/>
```

In your XSLT transformation, you want to write something like this:

```
(xsl/template {:match "a"} [:b])
```

Instead of this:

```
(xsl/template {:match "a"}
  (xsl/element {:name "b"}))
```

If you create a literal element with `[:b]`, though, clojure.data.xml puts it
into the empty namespace. That means that the XSLT stylesheet Sigel produces
will have this:

```xml
<xsl:template match="a">
  <!-- note the empty xmlns namespace declaration -->
  <b xmlns=""/>
</xsl:template>
```

When what you actually want is this:

```xml
<xsl:template match="a">
  <b/>
</xsl:template>
```

To do that, you must first set up your namespace with
`clojure.data.xml/alias-uri`:

```clojure
(xml/alias-uri 'my-ns "my-ns-uri")
```

You then need to set the `xmlns` attribute of your stylesheet and use the
`my-ns` prefix when emitting literal XML elements:

```clojure
(xsl/stylesheet {:version 3.0 :xmlns "my-ns-uri"}
  (xsl/template {:match "a"} [::my-ns/b]))
```

Functions for creating XSLT elements.

This namespace declares so many vars that conflict with vars in the
Clojure core that you probably want to alias the vars in this
namespace.
